Reversible -coordination of triallylphosphine in a trinuclear ruthenium carbonyl cluster
The triallylphosphine-substituted clusters [Ru3(CO)11{P(CH2CH=CH2)3}], [Ru3(CO)10{P(CH2CH=CH2)3}2] and [Ru3(CO)10{;-CH2=CHCH2P(CH2CH=CH2)2}] have been prepared; reaction of [Ru3(CO)10{;-CH2=CHCH2P(CH2CH=CH2)2}] with phosphines/phosphites leads to cleavage of the Ru–allyl -bond and formation of [Ru3(CO)11{P(CH2CH=CH2)3}(PR3)].
