Substitution of PPh3 from the bidentate acetatohydridoruthenium(II) complex RuH(CH3OCO)(PPh3)3 with various ligands, L, leads to unidentate acetatohydrido compounds with replacement of one, two or all PPh3 ligands depending on L (L = t-BuNC, PF2NMe2, P(OCH2)3CMe, P(OMe)3, dppe). On the other hand acetic acid elimination from RuH(CH3OCO)(PPh3)3 occurs with fluorophosphines to yield zerovalent ruthenium
PPH的取代3从二齿acetatohydridoruthenium(II)络合物期RuH(CH 3 OCO)(PPH 3)3与各种配位体,L,导致具有替代一个,两个或所有PPH单齿acetatohydrido化合物3根据对L-配位体(L = t-BuNC,PF 2 NMe 2,P(OCH 2)3 CMe,P(OMe)3,dppe)。从期RuH另一方面乙酸消除(CH 3 OCO)(PPH 3)3与fluorophosphines发生以产生零价的钌络合物RUL' 5(L'= PF 2 NME 2,PF 2 NC 4 H 8),RuL 4(PPh 3)(L'= PF 3)和RuL 3(PPh 3)2(L'= PF 3)。
