Bis-dimethylaminophenylphosphine reacts with α-halogeno esters and ketones to give hygroscopic quaternary phosphonium salts, leading to ill-defined betaines which readily undergo the WITTIG reaction with benzaldehyde. In alcohol solution, the reaction with phenacyl chloride gives the corresponding ketone, dialkyl phenyl-phosphonate and amine hydrochloride. A mixture of trimethylammonium and tetra-methylammonium
双二甲基氨基苯基膦与α-卤代酯和酮反应生成吸湿性季phospho盐,导致不明确的甜菜碱,很容易与苯甲醛进行WITTIG反应。在乙醇溶液中,与苯甲酰氯反应,得到相应的酮,苯基膦酸二烷基酯和盐酸胺。三甲基氯化铵和四甲基氯化铵的混合物已从甲醇中获得,而二甲基氯化铵仅从乙醇中获得。这些观察结果可以通过在甲醇中的三甲氧基phosph中间体的双分子(S N 2)脱烷基化和在乙醇中的相应的三乙氧基oxy中间体的单分子(S N 1)脱烷基化来解释。

Attempts to synthesise phosphinic amides for use as intermediates in the study of “metaphosphate” type compounds are described. In the case of phenyl phosphinic amides the attempts were defeated by the intermediateformation of phenylphosphinicanhydride which undergoes a facile and remarkable decomposition to give phenylphosphonic acid, tetraphenylcyclotetraphosphine, and phenylphosphine. The mechanism

Suzuki-Miyaura coupling was achieved on a variety of aryl chlorides by using di(2,6-dimethylmorpholino)phenylphosphine (Ll) as a bulky electron-rich monoaryl phosphine ligand. We report the couplings of various chlorobenzenes and heteroaryl chlorides. (c) 2006 Elsevier Ltd. All rights reserved.
