1,8-Diazabicycloundec-7-ene as a ligand in an intermediate in selective carbonyl substitution of a ruthenium-cobalt complex

1,8-Diazabicycloundec-7-ene, DBU, reacts with (OC)4Ru(μ-PPh2)Co(CO)3 (1) at room temperature to give an intermediate 2, which on protonation in the presence of CO regenerates 1 and on protonation in the presence of PMe3 gives the monosubstituted product (OC)3(L)Ru(μ-PPh2)Co(CO)3 (3 L=PMe3).DBU promotes the selective formation of 4 (L=PPh2Me) or 5 (L=Ph2PCH2C(Me)=CH2) in one-step from 1, Ph2PH, and methyl iodide or methallyl chloride, respectively.

INFLUENCE OF WATER ON THE KINETICS OF THE REACTION OF NITROALKANES WITH AMINE BASES IN APROTIC SOLVENTS

The traces of water in reaction systems of nitroalkanes and amine bases in aprotic solvents caused a marked decrease of the reaction rate instead of its acceleration expected from possible triggering of side reactions effected by hydroxide ions or hydroxide ion pairs BH+, OH-.The kinetics and possible consequences in the mechanism of proton transfer are discussed.
