Two Polish coals are subjected to the reactions of reduction and reductive alkylation in the system potassium/liquid ammonia. The classical methods of reduction and reductive alkylation of coal are modified by replacing the conventional protonating and alkylating agents by the ones containing deuterium atoms. Reduction is performed with C 2 H 5 OD whereas reductive alkylation with...
The vanadium imido complex ArNVCl 3 (2) (Ar = 2,6-C 6 H 3 -( i Pr) 2 ) can be converted to the half-sandwich imido vanadium complex CpV(NAr)Cl 2 (3) by reaction with CpSiMe 3 . Reaction of 3 and of CpV(N-p-tolyl)Cl 2 (1) with alkylating reagents did not allow the isolation of the pure dialkyl complexes but showed extensive reduction...
