摘要：

Phase transfer catalysed alkylation of 4-hydroxy dithiocoumarin (3) with a number of 1-aryloxy-4-chloro-but-2-ynes (4) furnished several 2-(4'-aryloxy-but-2'-ynyl thio)-[1]-benzothiopyran-4-ones (5) which when heated in chlorobenzene gave hitherto unreported 4-(aryloxymethyl)thiopyrano[2,3-b] benzothiopyran-5(2H)-ones (2) in excellent yields.
