Abstract

Abstract While o-substituted bromobenzene derivatives of the type o-BrC 6 H 4 XER n (X O, S; ER n SiMe 3 and N-BuLi undergo metal halogen exchange followed by silyl-X å C rearrangement, the corresponding compounds of phosphorus, arsenic or tin are split at the E X bond. o-Metal derivatives oM 1 C 6 H 4 XER n (X O, NMe; E P, As, Sn) of these elements may be generated, however, by direct reaction with sodium or lithium. They are ...
