reacts with gold(I) or gold(III) compounds to give dinuclear [Au(C6F5)]2[(PPh2)2CCH2] or [AuPPh2C(CH2)Ph2P)]2(ClO4)2] or mononuclear complexes ([Au(C6F5)3(PPh2C(CH2)Ph2P)]}, respectively. The latter reacts with gold(I) or silver(I) compounds to afford dinuclear [[Au(C6F5)3[PPh2C(CH2)Ph2P}AuX], XCl or C6F5) or trinuclear species [Au(C6F5)3PPh2C(CH2)Ph2P]2M]ClO4, MAu or Ag}. No addition of nucleophiles
亚乙烯基双(二苯基膦)与金(I)或金(III)化合物反应生成双核[Au(C 6 F 5)] 2 [(PPh 2)2 CCH 2 ]或[Au PPh 2 C(CH 2)Ph 2 P)] 2(ClO 4)2 ]或单核络合物([Au(C 6 F 5)3(PPh 2 C(CH 2)Ph 2 P)]}}。后者与金( I)或银(I)化合物制得双核[[Au(C 6 F 5)3[PPh 2 C(CH 2)Ph 2 P} AuX],XCl或C 6 F 5)或三核物种[Au(C 6 F 5)3 PPh 2 C(CH 2)Ph 2 P ] 2 M] ClO 4,MAu或Ag}。在这些络合物中没有观察到亲核试剂加到CC双键上,这些络合物含有作为桥接或单齿配体的二膦。(SPPh 2)2 CCH 2与AgClO 4反应得到[Ag SPPh 2 C(CH 2)Ph 2 PS}]2-(ClO 4)2或[Ag
