Reaction of Carbonyl Oxides and Thioketones. Cycloaddition vs. Oxygen Atom Transfer

Tabuchi, Toshihiko,Nojima, Masatomo,Kusabayashi, Shigekazu

, p. 625 - 627 (1990)

The ozonolysis of vinyl ethers (1a, b) in the presence of thioadamantan-2-one (4a) gave in each case the corresponding thio-ozonide (5a, b) in around 70percent yield, whilst ozonolysis of a mixture of vinyl ethers (1a-c) and thiobenzophenone derivatives (4b-d) gave the corresponding thione-S-oxides (8b-d) in 15-30percent yields, together with the benzophenones (6b-d).
