CPh2(CH2CH2Br)COOH did not undergo CO release when allowed to interact with WCl6, instead selective intramolecular condensation to C(Ph)2C(O)OCH2CH2, 7, occurred. MeCCCOOH underwent hydrochlorination by WCl6 to give MeC(Cl)CHCOOH, 8, in 72% yield. All the products were fully characterized by elemental analysis, IR and multinuclear NMR spectroscopy. In addition, the solid state structures of 1, 2, 4, 7, and 8 were elucidated
在环境温度下,三苯基乙酸在二氯甲烷中与一系列最高氧化态的4-6族金属的卤化物反应时,会经历异常的脱羰反应。因此,CPh 3 COOH与MoCl 5的摩尔比为1:1,以79%的收率得到三苯甲基盐[CPh 3 ] [MoOCl 4 ] 1,而CPh 3 COOH与MoCl 5的1:2反应。NbF 5以70%的收率提供[CPh 3 ] [NbF 6 ],2,NbOF 3是金属副产物。CPh 3 COOH与NbCl 5,TiF 4反应用WOCl 4和WOCl 4生成化合物的混合物,但是在每种情况下都通过NMR鉴定了阳离子[CPh 3 ] +。在从CPh 3 COOH和PCl 5生成之前,从NbCl 5和CPh 3 COCl中分离出[CPh 3 ] [NbCl 6 ],3。CPH的反应3 COOH用TiCl 4 4是非选择性的,并且所述盐[器CPh 3 ] [钛2氯8(μ-κ 2 -O 2 CCPh
