✦ Synopsis

The treatment of SH-benzo[f+l,2,3,4+enathiepin ( B'lTP ) or 6H-benzo[g]-l,2,3,4,5-pentathiocin ( BFTC ) with alkenes in the presence of BF3aEt2 afforded trclns adducts, 2,3disubstituted ben~l, (1). which further reacted with alkenes to give cis adducts, 2,3disubstituted benz~l.4ditbiepanes

(2).
