Effect of Various Additives. From the results mentioned above, it is evident that the copper stearate is converted to inhibitors by the interactions of oxidation products, and the oxygen uptake appears to level oflF after a certain time. Thus, the effects of model compounds of oxidation products (n-octylaldehyde, n-octanoic acid, 2-octanone, n-octanol, and n-octanoic aCid methyl ester), tert-hutyl hydroperoxide, and di-ter -butyl peroxide on the thermal oxidation of the polypropylene in trichlorobenzene were examined.

In other studies we have been investigating the production of nonnatural PHAs by an aerobic bacterium, P. oleovorans, and are presently testing the limits to which this bacterium will incorporate either sterically-hindered or functionalized units into the storage copolyesters it produces. In our study of steric effects this bacterium was fed a series of methyl-substituted octanoic acids to determine how rapidly and to what cell densities it could grow on these substrates, when they were used as either the sole carbon source or in combination with n-octanoic... 

Ethers are oxidized to esters by benzyltriethylammonium permanganate for example benzyl n-butyl ether gives butyl benzoate (90%) and methyl n-octyl ether is converted into methyl octanoate (41%). However, it must be added that this reagent explodes violently when heated or subjected to shock it should not be stored for any length of time. Alcohols (RCH2OH) can be directly oxidized to esters (RCO2CH2R) electrolytically in ca. 80% yield when iodonium ions are used as catalytic electron carriers. ...

A very marked effect of specific interactions can also be observed with anthroyl derivatives and in particular with methyl 8-(2-anthroyl)-octanoate. The fluorescence spectrum of this compound in hexane exhibits a clear vibrational structure, whereas in N,N-dimethylformamide and ethanol, the loss of vibrational structure is accompanied by a pronounced red-shift (Figure 7.6) (Perochon et al., 1991).

The maximum of emission is located at 430, 450 and 485 nm, respectively (excitation wavelength 360 nm) (reproduced with permission from Perochon et al., 1991).

Polymerization of the bulky monomer chloral yields an optically active product when one uses a chiral initiator, e.g., lithium salts of methyl (+)- or (—)-mandelate or (R)- or (S)-octanoate [Corley et al., 1988 Jaycox and Vogl, 1990 Qin et al., 1995 Vogl, 2000], The chiral initiator forces propagation to proceed to form an excess of one of the two enantiomeric helices. The same driving force has been observed in the polymerization of triphenyl-methyl methacrylate at —78°C in toluene by initiating polymerization with a chiral complex formed from an achiral initiator such as n-butyllithium and an optically active amine such as (+)-l-(2-pyrrolidinylmethyl)pyrrolidine [Isobe et al., 2001b Nakano and Okamoto, 2000 Nakano et al., 2001]. Such polymerizations that proceed in an unsymmetrical manner to form an excess of one enantiomer are referred to as asymmetric polymerizations [Hatada et al., 2002]. Asymmetric polymerization has also been observed in the radical... 

The formation and intramolecular dipolar cycloaddition of azomethine ylides formed by carbenoid reaction with C=N bonds has recently been studied by the authors group.84 Treatment of 2-(diazoace-tyl)benzaldehyde O-methyl oxime (176) with rhodium(II) octanoate in the presence of dimethyl acetylenedicarboxylate or N-phenylmaleimide produced cycloadducts 178 and 179, respectively. The cycloaddition was also carried out using p-quinone as the dipolarophile. The major product isolated corresponded to cycloadduct 180. The subsequent reaction of this material with excess acetic anhydride in pyridine afforded diacetate 181 in 67% overall yield from 176. The latter compound incorporates the basic dibenzofa, d -cyclohepten-5,10-imine skeleton found in MK-801,85 which is a selective ligand for brain cyclidine (PCP) receptors that has attracted considerable attention as a potent anticonvulsive and neuro-protective agent.86,87...
