✦ Synopsis


Recently-described work1 on the ene-reaction between acrylonitrile and ergosteryl acetate to give the adducts (I-III) leads us to report our investigation of some unusual reactions of tetracyanoethylene with three steroidal cisoid dienes. Tetracysnoethylene reacted rapidly with ergosteryl acetate in benzene solution to give a 1:l adduct, C H N 0 36 46 4 2,** m.p. 135", [al, 25 -170" in
