应用
氰化四丁基胺可用作催化剂:
- 在质子溶剂存在下,用于脱保护脂肪族硫醋酸酯,以合成自由硫基
- 在三甲基氰硅烷(TMSCN)存在下,用于羰基化合物的O-TMS 氰硅化反应,以合成氰丙烷三甲基硅醚.
- 在乙腈的存在下,通过对β-内酰胺键裂合成γ内酰胺,进而实现β-内酰胺的环扩展.

Tetrabutylammonium cyanide (20 mol %) catalyzes ring expansion of 4-(arylimino)methylazetidin-2-ones 2 to 5-aryliminopyrrolidin-2-ones 3 through a novel N1-C4 bond cleavage of the beta-lactam nucleus. New, efficient one-pot protocols to enantiopure succinimide derivatives 3 and 4 from beta-lactam aldehydes 1 have
