Hydrogenated diamond powder was treated with an anhydrous chloroform solution of 2, 2'-azobisisobutyronitrile as the radical initiator and sulfuryl chloride as the chlorination reagent at 323 K under an Ar atmosphere. After the chlorination process, the solution was exhaustively evaporated and n-butylamine was added without exposure to air. The diamond was then butylaminated at 303 K for 1-24 h. The treated diamond powder was washed with tetrahydrofuran and water to remove by-products, and characterized by infrared spectroscopy and flash pyrolysis. It could be confirmed that the hydrogenated diamond surface was modified by the radical reactions in the liquid phase. The similar results were obtained by using ethylenediamine, propylamine, triethylamine or phenethylamine.Chlorinated diamond was also treated with n-butyllithium, sodium azide, sodium methoxide or sodium ethoxide as the nucleophilic reagent. The formation of butyl, azide, methoxy and ethoxy groups on the diamond surface was not confirmed with FTIR and ESCA.The results might be due to the insufficient chlorination of diamond. Direct chlorination of diamond in the gas phase is carried out for the promoting covalent bonds between functional groups and carbon on the chlorinated diamond surface.

将氢化的钻石粉末用2、2'-二异异丁二吡啶腈的无水氯仿溶液作为激发剂，在AR大气下在323 K处作为氯化试剂作为自由基引发剂和氯化氯化物处理。氯化过程后，溶液彻底蒸发并添加N丁胺而不会暴露于空气。然后，钻石在303 K处被丁基固定1-24小时。用四氢呋喃和水洗涤处理过的钻石粉，以去除副产品，并以红外光谱和闪光热解的特征。可以证实，在液相中的自由基反应改变了氢化的钻石表面。通过使用乙二胺，丙胺，三乙胺或苯乙胺获得类似的结果。还用N-丁基锂，叠氮化钠，甲氧化钠或乙氧基钠作为核试剂处理氯化钻石。 FTIR和ESCA未证实钻石表面上丁基，叠氮化物，甲氧基和乙氧基团体的形成。结果可能是由于钻石的氯化不足所致。在气相中，钻石的直接氯化是为促进官能团之间的共价键和氯化钻石表面的碳的共价键。
