Cyclization Reaction of Bis(tributylstannylated) α-Ketols with Heterocumulenes. Preparation of O,O-Vinylene Imino- and Thiocarbonates

Article abstract of DOI:10.1246/bcsj.56.1873

Aromatic α-ketols reacted with diethylaminotributylstannane at 60 deg C to afford a mixture of (Z)- and (E)-1,2-bis(tributylstannyloxy)-1,2-diarylethenes, which were allowed to react with organic isothiocyanates and carbon disulfide to give substituted O,
