B. Wei et al., FACILE COMPLEXATION OF 1,1'-BIS(DIPHENYLPHOSPHINO) RUTHENOCENE (DPPR)TO RUTHENIUM(II) - SIMPLE ENTRY TO STABLE BIMETALLIC RUTHENORUTHENOCENYL SYSTEM, Journal of organometallic chemistry, 527(1-2), 1997, pp. 133-136
Phosphine exchange occurs rapidly between RuCl2(PPh(3))(n) (n = 3, 4)
and Ru(C(5)H(4)PPh(2))(2) (dppr) at room temperature to give RuCl2(dpp
r)(PPh(3)), 1. Triphenylphosphine is more substitutionally labile than
dppr in 1; selective phosphine substitution of 1 with CO and CH3CN gi
ves [RuCl2(CO)(dppr)] and two geometric isomers of [RuCl2(NCCH3)(2)(dp
pr)] respectively.
