Cl3SiR或(ETO)(3)SIR与[PW11O39](7-)反应生成双取代杂化阴离子[PW11O39(SIR)(2)O](3-)。用固体红外光谱、多核核磁共振(H-1、Si-29、P-31和W-183)和溶液循环伏安法对这些物种进行了表征。用Et3SiH和PhSiMe2H实现了[PW11O39(Si-CH=CH2)(2)O](3-)的硅氢化反应。这是杂化钨磷酸盐核心上的硅氢化反应的第一个例子。杂交种的显色行为已在溶液中得到证实。(C)2006爱思唯尔B.V.保留所有权利。
Reaction of Cl3SiR or (EtO)(3)SiR with [PW11O39](7-) affords the disubstituted hybrid anions [PW11O39(SiR)(2)O](3-). These species have been characterized by IR spectroscopy in the solid state and by multinuclear NMR (H-1, Si-29, P-31 and W-183) and cyclic voltammetry in solution. The hydrosilylation of [PW11O39(Si-CH=CH2)(2)O](3-) has been achieved with Et3SiH and PhSiMe2H. These are the first examples of hydrosilylation on a hybrid tungstophosphate core. The chromogenic behaviour of hybrid species has been demonstrated in solution. (c) 2006 Elsevier B.V. All rights reserved.
