While o-substituted bromobenzene derivatives of the type o-BrC6H4XERn (X O, S; ERn SiMe3 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 EX bond. o-Metal derivatives o-M1C6H4XERn (X O, NMe; E P, As, Sn) of these elements may be generated, however, by direct reaction with sodium or lithium
当o -BrC 6 H 4 XER n(X = O,S; ER n SiMe 3和N-BuLi类型)的邻位取代溴苯衍生物进行金属卤素交换,然后进行甲硅烷基-XåC重排时,相应的磷,砷或锡处于EX键分裂。ø -金属衍生物ö -M 1 C 6 ħ 4 XER ñ(XO,NME,EP,砷,锡)可以生成这些元素的但是,通过与钠或锂直接反应,它们不稳定,并提供邻羟基和邻羟基。-氨基苯基元素(IV,V)衍生物通过分子内阴离子重排。
