Abstract

Fully unsaturated group 14 (Si, Ge, and Sn), group 15 (P, As, Sb, and Bi) and group 16 (S, Se, and Te) 2-trimethylsilyl-1-benzoheteropines (16a-j), including the first isolated examples of bismepines, have been prepared by reaction of the corresponding electrophilic metal reagents (MX 2 or MX 4; M= group 14, 15, and 16 heavier elements) with the key 1, 6- dilithium intermediate (9), generated from the common starting compound (Z, Z)-1-bromo- ...
