摘要：

In situ IR monitoring of the Ni(CO)4/MeONa catalytic system for low temperature methanol synthesis has revealed the involvement of the [HNi(CO)3]- species in the catalysis. Two new methods for the synthesis of the anion were discovered and the model reactivity of [HNi(CO)3]- was also investigated. The overall results led us to suggest a catalytic cycle in which methanol is carbonylated to methyl formate with MeONa as the catalyst, while [HNi(CO)3]- catalyzes the hydrogenolysis of methyl formate to methanol.
