3-tetraethylisoindolin-2-oxyl, 2. The limiting step in their preparation is the Grignard reaction between N-benzylphthalimide and the appropriate alkyl magnesium bromide, which typically proceeds in yields of ~28–40%. A microwave-assisted variation of this reaction has been optimized to give improved yields and reduced reaction times (45–60% and 2 h, respectively).
1,1,3,3-四烷基异二氢
吲哚是制备稳定的氮氧化物的重要中间体,如 1,1,3,3-四甲基异二氢
吲哚-2-氧基、1 和 1,1,3,3-四乙基异二氢
