Intermolecular β-Hydrogen Abstraction in Ytterbium, Calcium, and Potassium Tris(dimethylsilyl)methyl Compounds

Redox chemistry of a hydroxyphenyl-substituted borane

Chemical reduction of a hydroxyphenyl-substituted borane triggers a sequential electron- and intramolecular hydrogen-atom-transfer process to afford a hydridoborate phenoxide dianion. On the other hand, hydrogen-atom abstraction of the borane leads to the isolation of a neutral borylated phenoxyl radical, which can be transformed to the corresponding benzoquinone borataalkene derivative by reduction with cobaltocene.

Selective reduction of CO2 to a methanol equivalent by B(C6F5)3-activated alkaline earth catalysis

Magnesium and calcium hydrido-tris(pentafluorophenyl)borate derivatives catalyse the completely selective reductive hydroboration of CO₂ with pinacolborane (HBpin) to provide the methanol equivalent, CH₃OBpin.

Direct hydrosilylation by a zirconacycle with β-hydrogen

The pendent β-SiH-containing zirconacycle and formaldehyde react to give a direct hydrosilylation product, similarly to the reaction of the non-classical zwitterionic compound.
