Oxathioles and oxathiolanes

The cyclic sulfinates 87 and 88 have been prepared by radical cyclisation of the corresponding haloalkyl ferf-butylsulfinates as shown 06AG(E)633. 

A review on reactions of 2-alkylidenethiiranes includes their reaction with carbonyl compounds, R32C=0, to give 4-alkylidene-l,3-oxathiolanes 88 07S2755 , and synthesis of the polyether-bridged bis(l,3-oxathiolane-2-thiones) 89 from the corresponding bis(epoxides) and CS2 with catalytic LiBr has been described 07PS2419 .
