Abstract:

The one-pot reaction of Bu3P-CS2 adduct with the compounds bearing unsaturated bonds (electric rich alkynes, phosphonyl alkynes or alkenes) and aldehyde affords dithioles or dithiolanes in mediocre yields. Bu3P-CS2 adduct reacts with azo-compounds and aldehyde to give the thiodiazolidine thiones. The mechanism of reaction is discussed.

Key words: Bu3P-CS2 adduct, l,3-dithioles, l,3-dithiolanes, thiodiazolidine thiones, cycloaddition
