A series of bromostannylenes, (Rind)BrSn: (1; Rind = EMind (a, R1 = Et, R2 = Me), Eind (b, R1 = R2 = Et), MPind (c, R1 = Me, R2 = nPr)), have been obtained as room-temperature thermally stable crystalline materials incorporating the fused-ring bulky Rind groups (Rind = 1,1,7,7-tetra-R1-3,3,5,5-tetra-R2-s-hydrindacen-4-yl). The bulky Eind- and the bulkier MPind-based bromostannylenes (1b,c) have been
一系列溴化苯,(Rind)BrSn: ( 1 ; Rind = EMind ( a , R 1 = Et, R 2 = Me), Eind ( b , R 1 = R 2 = Et), MPind ( c , R 1 = Me, R 2 = n Pr)),已作为室温热稳定结晶材料获得,包含稠环大 Rind 基团(Rind = 1,1,7,7-tetra-R 1 -3,3,5 ,5-四-R 2 - s -hydrindacen-4-基)。体积大的 Eind 和体积较大的 MPind 基溴化二甲苯 ( 1b , c) 已通过 SnBr 2 ·(二恶烷) 与 1 当量 (Rind) Li 在 THF 中的反应合成。相比之下,体积较小的基于 EMind 的卤代锡 (EMind)XSn: (X = Br ( 1a ), Cl ( 2a )) 是通过二芳基锡(EMind) 2 Sn: ( 3a ) 和
