Photochemical chlorination of nanodiamond and interaction of its modified surface with C-nucleophiles

A procedure for the photochemical chlorination of nanodiamond by molecular chlorine in the liquid phase was proposed. This process was studied quantitatively for the first time. Hydrolytic stability of the chlorinated nanodiamond surface in air and in a 0.05 M solution of NaOH was determined. A possibility of disintegration of the initial aggregates (< 60 mu m) to finer aggregates (< 200 nm) was shown. The reactions of a series of C-nucleophiles (organolithium reagents, CN- ion) with the chlorinated surface were carried out.
