✦ Synopsis
Triplet-sensitized photolysis of 2-methoxy-2,5,5-trimethyl-A3-I ,3,4-oxadiazoline
(1 a) led lo the retro-cleavage products diazoalkane 2a and the ester 3 a, for which the triplet diazenyl diradical 6a is postulated as precursor.
Warkentin et al.' recently reported that the 'photolysis of P-alkoxy-d-1,3,4-oxadiazolines produces diazoalkanes and esters. He pointed out that benzophenone sensitization had no noticeable effect on the
