Abstract

  • N,N-Dimethylethanolamine reacts with (CO) Mo(PPh Cl) to give (CO) Mo(PPh OCH CH NMe ) which has been characterized as a BF adduct and by heating to form the mixed donor (P,N) chelate complex (CO) Mo(PPh OCH CH NMe ). The chromium and tungsten analogs of the Mo chelate complex have been made by photochemical reaction between the hexa carbonyls and the uncomplexed (P,N) ligand. A combination of chloride displacemetn and photochemical chelation were used to obtain cis-(CO) Mo(PPh NHCH CH NMe ). With cis-(CO) Mo(PPh Cl) , HOCH CH NME gives cis-(CO) Mo(PPh OCH CH NMe )(PPh OH) and not the expected disubstituted product. Ethylenediamine, N-methylethylenediamine and N,N-dimethylethylenediamine react with cis-(CO) Mo(PPh Cl) in a straight forward manner to yield cis-(CO) Mo(PPh NHCH CH NR ) where R = H , HMe, and Me , respectively. N,N′-Dimethylethylenediamine yields only the chelate complex (CO) Mo(PPh NMeCH CH NMePPh ). The H NMR spectra of these complexes reveal some interesting examples of PH and HH virtual coupling. © 1980. 5 2 5 2 2 2 2 3 4 2 2 2 2 4 2 2 2 2 4 2 2 2 2 2 4 2 2 2 2 2 4 2 2 4 2 2 2 2 2 2 2 2 4 2 2 2 2 1
