Group 15 (P, As and Sb) and group 16 (S, Se, and Te) thieno[2,3-b]- (1), thieno[3,4-b]- (2), and thieno[3,2-b]heteroles (3) were prepared from the corresponding 1,4-dilithium intermediates, derived from (Z)-(β-bromo-β-trimethylsilylvinyl)thiophenes (6), (10), and (13) by treatment with tert-butyllithium, respectively. These thienoheteroles obtained are novel fused heterocyclicring systems, except for thienothiophenes and thienoselenophenes.
