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.

在Ar气氛下，以2,2'-偶氮二异丁腈为自由基引发剂，磺酰氯为氯化试剂的无水氯仿溶液在323 K下处理氢化金刚石粉末。氯化过程后，彻底蒸发溶液并在不暴露于空气的情况下添加正丁胺。然后将金刚石在 303 K 下丁胺化 1-24 小时。处理后的金刚石粉末用四氢呋喃和水洗涤以除去副产物，并通过红外光谱和快速热解进行表征。可以证实，氢化金刚石表面通过液相中的自由基反应进行了改性。使用乙二胺、丙胺、三乙胺或苯乙胺也得到了类似的结果。还用正丁基锂、叠氮化钠、甲醇钠或乙醇钠作为亲核试剂处理氯化金刚石。 FTIR和ESCA未证实金刚石表面形成丁基、叠氮化物、甲氧基和乙氧基。该结果可能是由于金刚石氯化不充分所致。在气相中对金刚石进行直接氯化是为了促进氯化金刚石表面上的官能团和碳之间的共价键。
