Pentakis trimethyl phosphite ruthenium

The white cyrstalline solid is very air sensitive and should be stored in sealed glass tubes. It is soluble in most solvents and is protonated by alcohols, giving [HRu[P(OCH3)3] s]+, which can be isolated as the tetraphenylborate salt. 

The complex displays a 3,P 1H nmr spectrum that is a single line in fast exchange and an A2B3 spin system in slow exchange.4  

The complex is soluble in tetrahydrofuran, chlorinated solvents, acetone, and
