Some fluoran compounds in Table 6 are found to form adducts with solvent. For example, when 6 -diethylamino-2 -(2,4-dimethylanilino)-3 -methylfluoran (77e) is recrystallized from toluene, it forms an adduct, mp 137-139°C, having 0.5mol of toluene of crystallization per mol of the fluoran the toluene of crystallization liberates on treatment with boiling n-hexane or isopropanol or on heating in vacuo. 2 -Anilino-6 -(N-cyclo-hexyl-N-methylaminoj-3 -methyl fluoran (77c) forms an adduct with...

In the area of organometallic chemistry, we begin with a procedure for the palladium-catalyzed animation of aryl halides and aryl triflates, illustrated by syntheses of N-HEXYL-2-METHYL-4-METHOXYANIUNE and N-METHYL-N-<4-CHLOROPHENYL)-ANILINE. The next procedure describes the synthesis of 1,2,3,4-TETRAHYDROCARBAZOLE by the palladium-catalyzed annulation of ketones with o-iodoaniline. Next, a procedure for the synthesis of 2,7-DIMETHYLNAPHTHALENE via the nickel-catalyzed coupling of aryl O-carbamates with Grignard reagents is presented. The fourth procedure in this section describes the synthesis of 5-METHYL-2,2 -BIPYRIDINE by a Negishi cross-coupling reaction...

As discussed above, the HOR and the closely related hydrogen evolution reaction (HER the reverse of Eq. 17.2) are of fundamental and applied interest to electrochemists and each has been studied in RTILs [33, 38, 60-62]. Compton and co-workers reported that the appearance and position of the HER peak during HOR/HER electrochemistry in RTILs depends on the stability of the protonated anion (the RTIL anions accommodate the protons generated during the HOR) and on the equilibrium position of the protonation reaction [60]. For example, the HOR is quasireversible in [N(Tf2)] -based RTILs while the reduction process is not observed at all in 1-hexyl-3-methyl imidazolium chloride and l-butyl-3-methyl imidazolium nitrate, indicating that the electrochemically generated protons react with the anions of the RTIL [60, 61]. 

This is a general method for making N-alkylallenimines, and the following ones have been made in this way N-methyl-,6 N-propyl-,6 N-isopropyl-,4 N-butyl-,4 N-hexyl-,e and N-(3,5,5-tri-methylhexyl)-.4 N-Z-Butylallenimine6 and l-(l-allenimino)-2-hydroxy-3-butene 7 have also been prepared by this method, but with sodium amide/2-bromoallylamine mole ratios of 1.75 and 2.1, respectively. This method has been used for the preparation of pure N-alkylpropargylamines from 2-chloroallylaminesA7 The optimum sodium amide/2-chloroallylamine ratio for the preparation of N-alkylpropargylamines is 2.1. 

Early studies of the asymmetric reduction of prochiral ketones by chiral aluminum alkoxides have been reviewed by Morrison and Mosher (1). Doering and Young (123) reported the reduction of methyl cyclohexyl ketone with chiral 3-methyl-2-butanol in the presence of a catalytic amount of aluminum alkoxide to give the (S)-( + )-carbinol in a 22% optical yield. Jackman and co-workers (124) similarly reduced methyl n-hexyl ketone with chiral 3,3-dimethyl-2-butanol to the (S)-( - )-carbinol in a 6% optical yield. Other attempts resulted in similar low optical yields or gave only racemic products. Since the reductions were carried out under equilibrium conditions, racemization could have accounted for the low optical yields. 

Similarly, acetylation of thieno[3,2-6]thiophene (2) afforded 2-acetyl-thieno[3,2-6]thiophene, which was converted into methyl n-hexyl ketone by desulfurization with Raney nickel. Oxidation of 2-acetylthieno-[3,2-i]thiophene followed by nitration gave 5-nitrothieno[3,2-6]-thiophene-2-carboxylic acid. Decarboxylation of the latter furnished 2-nitrothieno[3,2-ft]thiophene identical with the compound obtained by direct nitration of thienothiophene 2 [Eq. (60)].
