Formation and Reactions of Novel Heterocycles: 1,3,4-Oxadithiolane, 1,3,4-Oxadiselenolane, 1,3-Oxathietane,and 1,3-Oxaselenetane Derivatives

The reactions of 2,2,4,4-tetramethyl-1,5-diphenyl-1,5-pentanedione monohydrazone with S2Cl2 and Se2Cl2 gave 2,2,4,4-tetramethyl-1,5-diphenyl-8-oxa-6,7-dithiabicyclooctane (9) and 2,2,4,4-tetramethyl-1,5-diphenyl-8-oxa-6,7-diselenabicycloocta

Novel Heterocycles: 1,3,4-Oxadithiolane, 1,3,4-Oxadiselenolane, 1,3-Oxathietane and 1,3-Oxaselenetane Derivatives

The reaction of the monohydrazone 1 of 2,2,4,4-tetramethyl-1,5-diphenylpentane-1,5-dione with S2Cl2 affords a bicyclic 1,3,4-oxadithiolane derivative 2, which gives an equilibrium mixture of a 1,3-oxathietane 7 and its ring-opened isomer 6 on treatment wi
