Abstract:
The N -P-N-ligands RP(XC 5 H 4 N) 2 (1b′, c′, b″, c″) [X = O: R = t-Bu (b′), Me (c′); X = NH: R = t-Bu (b″), Me (c″)] are characterized by their different complex chemical behaviour towards group VI metal carbonyl derivatives. By reaction of 1b′, c′, b″, c″ with (CH 3 CN) 3 M(CO) 3 the complexes (OC) 3 M[RP(XC 5 H 4 N) 2 ] (2b′, c′, 3b″) and (OC) 4 W|[CH 3 P(NHC 5 H 4 N) 2 ] (3c″) [M = Mo (2).,W(3)] are formed in which the ligands are tridentate and bidentate, respectively. This difference can be explained with the existence of hydrogen bridge linkages between NH and pyridyl groups in 3c″. Homologation experiments of methanol with 1, CoOAc : and I 2 as an activator show high conversions (85%) with about 40% of ethanol selectivity. The lowest selectivities are found with 1c″.
