Hydrogen bonded to a diamond surface was chlorinated by radical reactions in chloroform. The disappearance of C-H stretching peaks showed that the majority of the C-H bonds were chlorinated by reaction at 50 for 8 h. Bromine selectively attacked carbons on the diamond (100) although the yield of bromination was lower than that for chlorination. The chlorinated diamond was then reacted with alkyllithium dissolved in THF at 30 for 4 h. Strong peaks assigned to C-H stretching and deformation after the alkylation indicated, for the first time, that the diamond can be successfully alkylated by relatively simple and straightforward organic reactions.
