    Abstract: Allylidene phosphoranes are prepared by a new process comprising reacting dialkyl aluminum alkylidene amides or bis(N-dialkyl aluminum-imino)alkanes which are obtainable from saturated aliphatic nitriles or dinitriles and dialkyl aluminum hydrides with alkylidene phosphoranes R3CH PR34. The allylidene phosphoranes are useful as intermediate products in the synthesis of 1,3-dienes which include insect attracting substances and flavoring agents, and in the synthesis of 1,5-dienes such as squalene.

    Abstract translation: 通过新的方法制备烯丙基膦,其包括可从饱和脂族腈或二腈和二烷基氢化铝得到的二烷基铝亚烷基酰胺或双(N-二烷基铝 - 亚氨基)烷烃与亚烷基膦R3CH = PR34反应。 烯丙基磷烷可用作合成1,3-二烯的中间产物,其包括昆虫吸引物质和调味剂,以及合成1,5-二烯如角鲨烯。
