ADDITION REACTIONS ON COORDINATED OLEFINIC LIGANDS .2. REACTION BETWEEN AMINES AND MONOOLEFINS COORDINATED IN CIS-DICHLORO(OLEFIN)(T-PHOSPHINE)PLATINUM(2) COMPLEXES

Treatment with amines of olefin complexes of the type cis-PtCl2(Ol)(PR3), in which Ol = ethylene, propene, and 1-butene and R = n-butyl and phenyl, led to isolable carbon-platinum σ-bonded derivatives. Dimethyl-, diethyl-, and dibutylamines were mainly used as the attacking nucleophiles. The behavior of ammonia, ethyl-amine, and triethylamine in the attack was also examined. The addition of the amine to the coordinated double bond was proved by degradative studies. Data on the stereochemistry of the addition of secondary amines to the tri-n-butylphosphine complexes were obtained. © 1969, American Chemical Society. All rights reserved.
