✦ Synopsis

the chemistry of biradicals obtained by a-cleavage of B,y-unsaturated ketones, we elected to examine the photochemistry of three compounds (l-3) which on a-cleavage could yield the same biradical. Fischer and Zeeh'l had examined the photochemistry of the A-homocholestenone 1 and reported that on direct irradiation 1 yielded a minor (MN) and major (MJ) photoproduct which they assigned (incorrectly, see below) as 2 and 3 respectively.
