IVa; R = 2,4,6-tBu3C6H2O: IVb) is described. IV reacts with Cp′(CO)3Mo−, VII, (Cp′ = η5-C5H5, η5-C5Me5) to yield bifunctionalized terminal phosphenium-ion complexes of the type (R)(Ph-CC)PMoCp′(CO)2 (R = 2,6-tBu2-4-MeC6H2O, Cp′ = η5-C5H5: IIa; R = 2,4,6-tBu3C6H2O, η5-C5H5: IIc, Cp′ = η5-C5Me5: IId). The compounds II contain a trigonal planar coordinated phosphorus atom, which is part of a phosphorus-molybdenum
苯乙炔基氯膦(R)(Cl)P(CCPh)(R = 2,6- t Bu 2 -4-MeC 6 H 2 O:IVa; R = 2,4,6-描述了t Bu 3 C 6 H 2 O:IVb)。IV发生反应与CP'(CO)3沫-,VII,(CP'=η 5 -C 5 H ^ 5,η 5 -C 5我5)纯化,得到双官能的类型(R)的终端phosphenium离子络合物(PH -CC)PMoCp'(CO)2(R = 2,6- t Bu 2 -4-MeC 6 H2 O,Cp'=η5 -C 5 H 5:IIa;m =1。R = 2,4,6-吨卜3 c ^ 6 ħ 2 O,η 5 -C 5 H ^ 5:IIC中,Cp'=η 5 -C 5我5:IID)。化合物II含有一个三角形的平面配位的磷原子,它是磷-钼双键系统的一部分。
