一般描述
2- 叔 -丁亚胺-2-二乙氨基-1，3-二甲基二氢-1，3，2-二氮杂膦 (BEMP) 是一种磷腈碱。BEMP 参与温和的碱催化 N -磺酰基氮杂环丙烷的亲核开环。以聚苯乙烯为载体的 BEMP (PS-BEMP) 是一种高效的酚醛开环催化剂。BEMP 比 DBU（l,8-二氮杂双环 [5.4.0] 十一烯）的碱性强 2000 倍，空间位阻也大很多。
应用
2- 叔 -丁亚胺-2-二乙氨基-1,3-二甲基二氢-1,3,2-二氮杂膦 (BEMP)，有机磷碱可用于以下研究：
- 2,3-二氢苯并 [1,4] 二氧杂萘-5-酮的合成。
- 作为碳酸烷基化反应的催化剂。
- 作为六元环碳酸盐可控“永生”开环聚合 (iROP) 中的有机催化剂。

First synthesis of a macrocylic cyclophane-based unusual alpha-amino acid derivative 11 by coupling of ethyl isocyanoacetate with 1,2-bis(4-bromomethylphenyl)ethane under phase-transfer catalysis (PTC) conditions. Phosphazene base such as 2-tert-butylimino-2-diethylamino-1,3-dimethylperhydro-1,3,2-diazaphosphorine (BEMP) is useful to improve the yield of cyclophane derivative without high
