In the formate esters, the free energy difference decreases from esters to thioesters and amides for the methyl and tert-butyl groups, and E-methyl formate is only observed in very small amounts (<0.3%) at low temperature (190 K), as shown by 13C NMR spectroscopy [3], The energy is significantly lower for the bulky tert-butyl moiety relative to the methyl group and this seems to be a function of steric hindrance since ethyl formate and iso-propyl formate have intermediary values [4,5]. In the tert-butyl formate, a strong electronic repulsion accounts for the relatively high proportion of E isomer (10%). 

Pimentel et al. (2010) studied the OH-radical-initiated oxidation of isopropyl formate in the presence of NOx and reported the following products (molar yields) acetic formic anhydride (43%), acetone (43%), and HCOOH (15-20%). From the observed formation of CH2O in the chlorine-atom-initiated oxidation of iso-propyl formate, Pimentel et al. (2010) deduced that the fate of 0CH2(CH3)CH0C(0)H alkoxy radicals is decomposition (rather than reaction with O2). The resulting alkyl radical (CH3)CH0C(0)H is converted into the alkoxy radical 0(CH3)CH0C(0)H which then decomposes via...

Successful results have been obtained (Renfrew and Chaney, 1946) with ethyl formate methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, sec.-butyl and iso-amyl acetat ethyleneglycol diacetate ethyl monochloro- and trichloro-acetates methyl, n-propyl, n-octyl and n-dodecyl propionates ethyl butyrate n-butyl and n-amyl valerates ethyl laurate ethyl lactate ethyl acetoacetate diethyl carbonate dimethyl and diethyl oxalates diethyl malonate diethyl adipate di-n-butyl tartrate ethyl phenylacetate methyl and ethyl benzoates methyl and ethyl salicylates diethyl and di-n-butyl phthalates. The method fails for vinyl acetate, ieri.-butyl acetate, n-octadecyl propionate, ethyl and >i-butyl stearate, phenyl, benzyl- and guaicol-acetate, methyl and ethyl cinnamate, diethyl sulphate and ethyl p-aminobenzoate. 

Polymer formation is still observed with some sterically hindered thiolates, 2,4,6-Ao-propyl thiophenolate, and 2,4,6-trimethyl thiophenolate complexes have been studied. They can be synthesized by the reaction of Zn[N(SiMe3)2]2 with the appropriate arene chalcogenol. With the least steric bulk, the trimethyl derivative forms coordination polymers that can only be dissolved in strongly coordinating solvents. The iso-propyl derivative is more soluble forming oligomers in solution. 1...

An interesting method for the introduction of substituents into the 2-position of the quinuclidine ring starting from 3-substituted A2-dehydroquinuclidines (126) has been described.47 By the reaction of methyl J2-dehydroquinuclidine-3-carboxylate (130) with iso-propylmagnesium bromide, 1,4-addition with formation of 2-iso-propyl-3-methoxycarbonylquinuclidine (131) took place instead of a sterically hindered Grignard reaction at the alkoxycarbonyl group. 

On the other hand, in a similar study recently carried out by Falconer et al. (41), no evidence was found for the presence of allyl radicals and the occurrence of reaction (23) appears unlikely. The products could be explained by assuming initial formation of hot iso- and n-propyl radicals. As will be discussed in the next section, 94% of iso- and 6% of propyl radicals are formed in this reaction. The further fate of both these radicals has to be considered, since hot n-propyl decomposes readily into C2H4 and CH3 but the same is not true for iso-propyl, where a simultaneous internal migration of an H atom must occur. 

Another family of inhibitors, hydrogen-donating agents such as iso-propyl and 1,4-di-ivo-propyl benzenes, was investigated by Lamouroux in order to reduce the formation of TBP-TBP dimers, which exhibit a very high plutonium retention of TBP (47). The presence of at least one mobile hydrogen on the iso-propyl group could produce a benzylic tertiary radical stabilized by resonance. The addition of such compounds reduced the concentration of the TBP-TBP dimers by about 50%. 

Ethoxycarbonylethyl-2-isopropyl-3-imidazoline (46) gave a separable mixture of 2,5-bis(2-ethoxycarbonylethyl)pyrazine (48, Q = H) and its 3-iso-propyl derivative (48, Q = IV) [trace TsOH, xylene, reflux, 1 h 21 and 38%, respectively postulated mechanism formation of dimer (47) and loss of FVC (=NH)H to give a dihydropyrazine that in part undergoes oxidation to product (48, R = H) and in part adds one of the foregoing fragments with subsequent oxidation to product (48, R = FV)].542...
