The oxo anions [WO4]2– and [ReO4]– react with the Lewis acid molecule [B(C6F5)3] to give the tris-adduct [WOOB(C6F5)3}3]2– or the mono adduct [ReO3OB(C6F5)3}]– respectively. The crystal structure of the salt [nPr4N]2[WOOB(C6F5)3}3] has been determined. The η-cyclopentadienyl-oxo compounds [Re(η-C5R5)O3] (where R = H or Me) react with [B(C6F5)3] giving the mono adducts [(η-C5R5)ReO2OB(C6F5)3}] and the crystal structure of the compound where R = H has been determined. The triazacyclononane compounds [LMO3] (where L = N,N′,N″-trimethyl-1,4,7-triazacyclononane and M = Mo or W) with [B(C6F5)3] give the mono adducts [LMO2OB(C6F5)3}] and the crystal structure of the tungsten compound is reported. The compound [ReHB(pz)3}O3] [where HB(pz)3} = hydridotris(1-pyrazolyl) borate] and [B(C6F5)3] gives the mono adduct [HB(pz)3ReO2OB(C6F5)3}].
氧化阴离子 [WO4]2- 和 [ReO4]- 与路易斯酸分子 [B(C6F5)3] 反应,分别生成三加合物 [WOOB(C6F5)3}3]2- 或单加合物 [ReO3OB(C6F5)3}]-。盐 [nPr4N]2[WOOB(C6F5)3}3] 的晶体结构已经确定。η-环戊二烯氧化合物 [Re(η-C5R5)O3](其中 R = H 或 Me)与 [B(C6F5)3] 反应生成单加合物 [(η-C5R5)ReO2OB(C6F5)3}],其中 R = H 的化合物的晶体结构已经确定。三氮杂环壬烷化合物 [LMO3](其中 L = N,N′,N″-三甲基-1,4,7-三氮杂环壬烷,M = Mo 或 W)与 [B(C6F5)3] 生成单加合物 [LMO2OB(C6F5)3}],并报告了钨化合物的晶体结构。化合物 [ReHB(pz)3}O3] [其中 HB(pz)3} = 三(1-吡唑基)硼酸氢化物] 和 [B(C6F5)3] 得到单加合物 [HB(pz)3ReO2OB(C6F5)3}]。
