Reaction between Ru(CO) 2(PPh 3) 3 and MeHgI yields Ru[η 2-C(O)CH 3]I(CO)(PPh 3) 2 which in solution exists mainly as RuCH 3I(CO) 2(PPh 3) 2 and crystal structure determination of Ru[η 2-C(O)CH 3]I(CO)(PPh 3) 2 and previously described... ...
An X-ray structural investigation of the product of the MeO2CCCCO2Me reaction with the related ruthenocycle [(3-MeC5H3N-2-C6H4)Ru(μ-I)(CO)2]2 demonstrates that the alkyne inserts into the RuC bond. Addition of LiCl retards the insertion markedly indicative of the importance of the ...
