Chloro-2-(7V-methylhydrazino)quinoxaline 4-oxide (227, R = H) gave 2-(N -acetyl-/V-methylhydrazino)-6-chloroquinoxaline 4-oxide (227, R = Ac) (Ac20, pyridine, dioxane, reflux, 30 min >95%) or 6-chloro-2-(A-methyl-/V -trifluoroacetylhydrazino)quinoxaline 4-oxide [CHCI3, (F3CC0)20, drop-wise, <5°C then reflux, 1 h 63%].496... 

Water soluble iron porphyrins [Fem(TPPS)(H20) ]3-330 and [Fem(TMPy)(H20)2]5+ 331 332 (TPPS = maso-tetrakis(/ -sulfonatophenyl)porphyrin, TMPyP = / /e.vo-tetrakis(7V-methyl-4-pyridi-nium)porphyrin331 or maso-tetrakis (A -methyl-2-pyridinium)porphyrin332 dications) act as effective electrocatalysts for the reduction of nitrite to ammonia in aqueous electrolytes (Equation (64) Ei/2= 0.103 V vs. SCE at pH 7), with NH2OH or N20 also appearing as products depending on the reaction conditions. Nitric oxide then ligates to the iron(III) porphyrin to form a nitrosyl complex [Fen(P)(NO+)] (P = porphyrin) as intermediate. 

Kinetic studies. HERON reactions of 7V-acyloxy-/V-alkoxyamides, which can be conveniently followed by NMR in <74-methanol by monitoring the disappearance of the mutagen or aniline and formation of ester and tetrazene, conform to classical bimolecular kinetics being first order in both mutagen and TV-methyl-aniline.41 43,46,105 Arrhenius parameters and bimolecular rate constants (308 K) for a range of /V- a cy 1 o x y - TV- a 1 k o x y a m i de s 25-30 are collated in Table 5.

Tertiary enamines are oxidized to different compounds. 7V-Methyl-pyrrol gives 92% of /V-methylsuccinimide by oxidation with peroxybenzoic acid in chloroform at room temperature [311]. A -Cyclohexenylmorpholine, with singlet oxygen, is oxidized to cyclohexanedione (equation 524) [42], The oxidation of Af-phenylacetylenyl-lV,Af-diethylamine yields the M diethylamide of phenylglyoxylic acid (equation 525) [7S6]. 

There are a variety of photochemical reactions involving free nitrous oxide (NO) as persistent radical. Often there is an initial fragmentation, as presented in Scheme 6 for TV, 7V-dimethyl-/V-nitro-samine. One example is the Barton reaction of nitrite esters (Scheme 15). It allows the functionalization of methyl groups in steroids and utilizes an intermediate 1,5-hydrogen atom migration, which converts the initially formed oxygen-centered radical to a carbon-centered species.69... 

Compounds of Group 1. - (6Li, 15N) and (6Li, 13C) couplings were observed for mixed complexes formed between LiCH2CN and chiral lithium amides (1H, 6Li, 13C, 15N data).1 7Li and 31P H) HMQC experiments were used to assign the structures of benzyllithium complexes of /V-methyl-/V-ben-zylphosphinamide, e.g. (I).2 111 and 13C NMR and 13C-111 correlation spectra were used to confirm the presence of a C-Si-Ni-Li 4-membered heterocycle in [benzylbis(dimethylamino)-methylsilyl-K2-C,7V](7V, N, N, N -tetramethylenedia-mine-K2-iV,/V)lithium(I).3... 

The standard electrode potential for Co /Co has been determined from a calorimetric study of the Co -Fe reaction. The value obtained (1.73 V) is somewhat lower than that estimated previously, possibly owing to differences in the perchloric acid concentrations used. The recommended figure 1.85 V (7 =25°C, 4M-HCIO4) is based on potentiometric measurements. The oxidations of acetamide, formamide, and 7V-methyl- and IViV-dimethyl-formamides have been studied in aqueous HCIO4. The rate law is of the form... 

Penton and Zollinger (1979, 1981 b) reported that this could indeed be the case. The coupling reactions of 3-methylaniline and A,7V-dimethylaniline with 4-methoxy-benzenediazonium tetrafluoroborate in dry acetonitrile showed a number of unusual characteristics, in particular an increase in the kinetic deuterium isotope effect with temperature. C-coupling occurs predominantly (>86% for 3-methylaniline), but on addition of tert-butylammonium chloride the rate became much faster, and triazenes were predominantly formed (with loss of a methyl group in the case of A V-di-methylaniline). Therefore, the initial attack of the diazonium ion is probably at the amine N-atom, and aminoazo formation occurs via rearrangement. 

Treating 2 -ani lino-6 -[/V-ethyl-/V-(3-methoxypropyl)ami no]-3 -methyl-fluoran (88) with 48% hydrobromic acid in the presence of concentrated sulfuric acid at 110-11 5 °C gives 2 -anilino-6 -[/V-(3 -bromopropyl)-7V-ethylamino]-3 -methylfluoran (89)70 in excellent yield (Eq. 10). 

The structure of [Ir(cod)(dppf)]PF6 shows approximately square-planar geometry at Ir, and the cp rings of the dppf ligand are close to parallel and staggered.592 The systems [Ir(cod)(LL)]C104, where LL = dppf, l-diphenylphosphino-2-(7V,7V-dimethylamino)methyl ferrocene and 1,6-diferrocene-2,5-diazahexane, catalytically trimerize PC=CH to 1,3,5-triphenylbenzene.593 The electrochemistry of [Ir(dppf)2]BPh4 shows two one-electron reductions at —1.560 V and -1.755 V vs. ferrocenium/ ferrocene.753... 

The first example of a stable geminal enediol derivative of a carboxylic acid, isolated as its platinum(II) complex, has been reported.324 Treatment of [Pt(OH2)2(en)]2+ with /V,/V-bis(phos-phonomethyl)aminoacetic acid yields zwitterionic [Pt(bpmaa)(en)] (bpmaaH = 7V,7V-bis(phosphono-methyl)aminoacetic add), which upon crystallization from water (pH 1) affords the corresponding enol tautomer (130), as determined by X-ray crystallography and IR spectroscopy. 

The derivative 90 was obtained by condensation of the purpurin-18-A-hexylimide-17-propionic acid with aminolactose heptaacetate in the presence of benzotriazol-l-yloxy-tris(dimethylamino)phosphonium hexafluorophosphate (BOP) followed by the deacetylation procedure. The lactose-photosensitiser conjugate linked by an ethylene moiety was also prepared by following a similar approach. The purpurin-18-methyl ester 81 was converted into /V-(3-iodobenzyl)/ /evo-purpurin-18-7V-hexylimide-17-propionic ester by hydrogenation over Pd/C followed by reaction with 3-iodo-benzylamine. Afterwards, the propargyllactose heptaacetate reacted with A-(3-iodobenzyl)rMeio-purpurin-18-A-hexylimide-l 7-propionic ester in the presence of tris(dibenzylidieneacetone)dipalladium(0) (Pd2-dba3) which, after deacetylation conditions, afforded the derivative 89 (Fig. 9).68... 

Diethyl 7V,./V-dimethylaminomethylenemalonate was obtained in the reaction of di-fm-butyl[bis(dimethylamino)methyl]phosphine and diethyl malonate at 80-100°C for 1 hr in 45% yield (88ZOB1445 89ZOB2206).
