General description

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。

Application

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。

磷腈碱：一族非常强的、非离子型的、不带电荷的氮碱

Organocatalysts for the controlled "immortal" ring-opening polymerization of six-membered-ring cyclic carbonates: a metal-free, green process.

Marion Helou et al.

Chemistry (Weinheim an der Bergstrasse, Germany), 16(46), 13805-13813 (2010-10-15)

Six-membered cyclic carbonates, namely trimethylene carbonate (TMC), 3,3-dimethoxytrimethylene carbonate (DMTMC) and 3-benzyloxytrimethylene carbonate (BTMC), undergo controlled "immortal" ring-opening polymerization (iROP) under mild conditions (bulk, 60-150 °C), by using organocatalysts, including an amine [4-N,N-dimethylaminopyridine (DMAP)], a guanidine [1,5,7-triazabicyclo-[4.4.0]dec-5-ene (TBD)], or a

Efficient base catalyzed alkylation reactions with aziridine electrophiles.

Thomas A Moss et al.

Chemical communications (Cambridge, England), (21)(21), 2474-2476 (2008-05-21)

N-Mesitylene sulfonyl and N-tosyl aziridines have been identified as effective electrophiles in alkylation reactions of carbon acids catalyzed by the organic phosphorine base BEMP; yields of up to 99% for a range of pro-nucleophiles under mild reaction conditions are reported.

E-Factor minimized hydrophosphonylation of aldehydes catalyzed by polystyryl-BEMP under solvent-free conditions.

Tommaso Angelini et al.

Organic & biomolecular chemistry, 11(30), 5042-5046 (2013-06-28)

An efficient protocol for the hydrophosphonylation of aromatic and aliphatic aldehydes catalyzed by PS-BEMP under solvent-free conditions (SolFC) has been reported. Addition reactions were performed by using equimolar amounts of reagents and the resulting α-hydroxyphosphonates were isolated with simple workup
