文摘
[Rh(dmgH)2(PPh3)[− (dmgH2 = dimethylglyoxime), prepared by reduction of [Rh(dmgH)2(PPh3)Cl] with NaBH4 in methanolic KOH, reacts with (E)-1,2-dichloro ethylene to give the (E)-vinylene-bridged dinuclear rhodium complex [{K(MeOH)2}2-{(PPh3)(dmg)(dmgH)Rh-CH=CH-Rh(dmg)(dmgH)(PPh3)}] (1). Furthermore, 1 is formed in a mixture with [Rh(dmgH)2(PPh3)(Z-CH=CHCl] (2) and [Rh(dmgH)2(PPh3)CH=CH2 (3) in the reaction of [Rh(dmgH)2(PPh3)]− with (Z)-ClCH=CHCl and in a mixture with 3 in the reaction of [Rh(dmgH)2(PPh3)]− with acetylene.
