The formation of 1,3-diketones was observed in the reactions of bulky acyl chlorides with methyllithium. The reaction products depend on the steric hindrance around the carbonyl group of the acyl chloride and the electronic effect of the group(s) linked to the carbonyl. When the steric hindrance around the carbonyl group of the acyl chloride is big enough, the 1,3-diketone is the only product. In the case of the moderate hindrance around the carbonyl group of the acyl chloride, a moderate yield of 1,3-diketone is obtained and some tertiary alcohol is generated. When there is no steric hindrance around the carbonyl group of the acyl chloride, the tertiary alcohol is the only product. When the steric hindrance around the carbonyl group is moderate and an electron-donating group is connected to the carbonyl of the acyl chloride, all three products-ketone, 1,3-diketone and tertiary alcohol-can be isolated from the reaction mixture after long reaction times.

Utilization of a triptoxy radical probe in the reactions of organometallic compounds with 2,3,3-trimethyl-2-butyl peroxybenzoate indicates that the radical character of the reaction decreases in the order n-BuLi>n-BuMgCl>PhMgBr.
ARE α-ALKOXYALKYL COMPLEXES SPECIAL? 13C-H COUPLING CONSTANT EVIDENCE

Complexes of type LnMCH2O2CCMe3 exhibit relatively large values of 1JCH for the α-carbon; however, unexpectedly large values are also found for the methyl analogs, LnMCH3.Thus this technique does not provide evidence for any unusual
