unexpected amount of Ph−Se bond cleavage (35% in n-hexane at 248 nm) during photolysis. Solvent viscosity, wavelength of light, and the structure of alkyl substituents were the major factors that controlled Ph−Se bond cleavage. The ratio of Ph−Se bond cleavage decreased with increasing solvent viscosity and laser wavelength. The effect of alkyl substituents on the ratio of bond cleavages, Ph−Se/total C−Se
The dissolution of a stainless steel anode provides catalytic nickel species which enable the efficient synthesis of ketones by electrolysis of organic halides in DMF in the presence of bipyridine and carbon monoxide.

A survey of the reaction of nitrogen trifluoride (NF3) with various organometallic reagents finds that organomagnesium (Grignard) reagents are the most useful for producing N,N-difluoroaminoalkanes. Alkyl–alkyl coupling is a persistant side reaction. Organolithiums are marginally effective. Organocopper, organozinc reagents undergo primarily alkyl–alkyl coupling catalyzed by the presence of NF3.
