Reactions of Laser-Ablated Boron Atoms with Methanol. Infrared Spectra and ab Initio Calculations of CH3BO, CH2BOH, and CH2BO in Solid Argon

This is the authors' abstract. We don't add key points for this paper.

Laser-ablated boron atoms react with methanol to give primarily CH 3 BO, which is isolated in an argon matrix. FTIR spectra of various isotopic combinations and MP2 calculated isotopic frequencies help identify this product and the minor products, CH 2 BOH and CH 2 BO. All new products form via boron insertion into the C−O bond, while HBO and DBO form via boron insertion into the O−H bond; no C−H insertion products can be observed. All of these products contain partial dative B−O bonds in which an oxygen lone pair bonds with the empty boron p-orbital.
