The sequential installation of a carbenoid and a hydride into a carbonyl, furnishing halomethyl alkyl derivatives, is reported. Despite the employment of carbenoids as nucleophiles in reactions with carbon-centered electrophiles, sp3-type alkyl halides remain elusive materials for selective one-carbon homologations. Our tactic levers on using carbonyls as starting materials and enables uniformly high yields and chemocontrol. The tactic is flexible and is not limited to carbenoids. Also, diverse carbanion-like species can act as nucleophiles, thus making it of general applicability.

Pulse radiolysis of 1,1-diphenylethylene (DPE) in methanol in the presence of oxygen, as well as of 1,1-diphenyl-2-chloroethylene (DPE-2-Cl), 1,1-diphenyl-1-chloroethane (DP-1-Cl-Et) and 1,1-diphenyl-2-chloroethane (DP-2-Cl-Et) in methanol saturated with argon, was performed.The products formed under pulse-radiolysis conditions were also analysed.Spectroscopic and kinetic data of the corresponding transiets are presented.The reaction rate constants determined in methanol are .It has been established that the solutes are primarily attacked by e-s and H, whereas the CH2OH species (or O2) react with the intermediates thus produced.Reaction mechanisms consistent with the spectroscopic and kinetic data are presented.
