Abstract¡G
¤@¡B trans o-Thiomethoxystilbene and its derivatives 19a-c had been studied by means of pyrolysis and photolysis. Under pyrolytic conditions, compounds 19a-c gave not only the products 24¡B30¡B33,but also their corresponding isomers 26¡B31¡B34 . Furthermore, compound 19c gave dibenzothiophene (32) as the major product by opening the furan ring at higher temperature. Under photolytic conditions, compounds 19a-c gave the corresponding photocyclic products 40¡B44¡B46. With the exception of 19c, photolysis of 19a and 19b also gave 24 and 30, respectively.
¤G¡B For synthetic study of thieno-fused derivatives 4 and 5 of truxene, preparation monomer 6 and 7 can be accomplished in two steps by means of flash vacuum pyrolysis.
