in tetrahydrofuran Kinetics; byproducts: CO; under inert atmosphere, slight excess of (PPN)Re(CO)5, stirred for a week, at 25°C; THF remove, extracted with hexane, IR;
in tetrahydrofuran Kinetics; byproducts: CO; under inert atmosphere, slight excess of (PPN)Re(CO)5, stirred for 3 h, at 25°C; THF remove, extracted with hexane, IR;
in acetonitrile Kinetics; react. of the metal carbonyl anion (0.001 M) with an excess of the Co(III) complex (0.10-0.30 M) at 25°C in CH3CN with addn. of excess (NBu4)(BF4) (0.01-0.04 M); detn. by decrease of the IR intensity of the metal carbonyl anion;
