摘要: 本文报道α-噻吩甲酰基次甲基三苯胂及其与酸酐、酰卤的反应,分别获得相应的双酮胂叶立德(2a-d)和季钟盐烯醇酯衍生物(3a~f)。后者在碱溶液中加热,可生成胂叶立德(2c,d)或者胂叶立德(1),产物经元素分析、红外光谱、核磁共振谱和质谱鉴定,确定了结构。

Abstract: This paper presents the mass spectrum of α-thenoylacylmethyltriphenylarsine (1) and its reactions with acid anhydrides and acyl halides. The fragment peaks pf arspnium ylide (1) are shpwn.Arspnium ylide (1) reacted with a variety pf acid anhydrides tp fprm new stable derivatives pf the corresppnding diketoarsonium ylides (2a-d) at 30-60℃; in benzene. Acylation of arsonium ylide (1) with acyl halides in benzene led to enol-ester derivatives (3a-f). We alsp found that when arsonium ylides (3c,d) was heated in basic trichloromethane, diketoarsonium ylides (4d) and arsonium ylide (1) was obtained. The structures of products have been ascertained by elemental analysis, IRand 1H NMRspectroscopies.

Key words: Arsonium ylide, Acylation, Organoarsenic compound
