乙酰基群的

Treatment of N-p-tolylsulfonylindole 1 with acetyl chloride in dried dichloromethane gave the title compound, N-p-tolylsulfonyl-3-acetyl-indole 2 C17H15NO3S, M(subscript r=313.36 in 89% yield. Single-crystal structure of 2 was determined by X-ray crystallography.2 crystallizes in the triclinic system, space group P-1 with a=10.0264(13), b=12.5913(16), c=14.1621(18)?

N-对－甲苯磺酰－吲哚(1)在二氯甲烷中与乙酰基氯反应得到产率为89%的N-对－甲苯磺酰－3-乙酰基－吲哚(2)（分子式：C17H15NO3S，分子量：313.36），用单晶X-射线衍射方法测定了2的晶体结构并表明：属三斜晶系，空间群为P-1，单胞参数为a=10.0264(13)，b=12.5913(16)，c=14.1621(18)？

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
