摘要
报道了以双 (二苯膦基 )乙撑为中间体合成磷杂大环 4,7,1 3,1 6 -四苯基 -1 ,1 0 -二氧杂 -4 ,7,1 3,1 6 -四磷杂环十八烷的方法。产物经元素分析、1HNMR和 MS证实其结构。
This paper reports the synthesis of 4,7,13,16—tetraphenyl—1,10—dioxa—4,7,13,16—tetraphosphacyclo—oc—tadecane by using 1,2—bis (diphenylphosphino)ethane asthe key intermediate which is ordinarily employed as lig—and for transition metals.The experimental procedure ofthis synthesis was described and the structure of thephosphamacrocycle was identified by elemental analysis,MS and 1HNMR spectra.
