Abstract

The reaction of CO2 with Et3SiH catalyzed by the nickel complex [(dippe) Ni (μ-H)] 2 (1) afforded the reduction products Et3SiOCH2OSiEt3 (12%), Et3SiOCH3 (3%), and CO, which were characterized by standard spectroscopic methods. Part of the generated CO was found as the complex [(dippe) Ni (CO)] 2 (2), which was characterized by single-crystal X-ray diffraction. When the same reaction was carried out in the presence of a Lewis acid, such ...
