N,N-Dimethylformamide-Mediated Sodium Reduction of trans-3,3‘-Benzo[c]thienylidene-1,1‘-dithione and trans-3,3‘-Benzo[c]selenonylidene-1,1‘-dithione
摘要:
The synthesis of stable methylthio-capped biisothianaphthene and biisoselenophene derivatives has been achieved using DMF-mediated sodium reduction of cyclic thiocarbonyl compounds.

Treatment of the dithiolane derivative of an ol-carboxyethyl benzaldehyde with LDA at -78 degreesC smoothly produced the thiothionophthalic anhydride. The mechanism is proposed to involve loss of ethene and attack of an intermediate dithiocarboxylate onto the ester. Heating the thiothionophthalic an hydride gave the 3,3'-bithiophthalide.
