Abstract
Radicals a to the carbonyl of ethyl 3,4,4-trimethylpentanoate couple w ith little stereoselectivity while analogous tertiary radicals derived from ethyl 2,3,4,4-tetramethylpentanoate disproportionate at 25 degre es C to give the corresponding alkene and alkane. The alkane is formed by disproportionation with a diastereoselectivity of greater than 20: 1.
