CAS: 1101-41-3; Tetraphenylbiphosphine

该化合物是有机磷化合物,其独特结构特征是两种磷原子结合,各附于两个苯基组,在室温下,这种化合物一般没有颜色,可粉色,黄色固体,以其稳定性和低挥发性而著称;四苯基二酚具有令人感兴趣的化学特性,包括作为悬浮体与各种金属相协调的化学混合物的能力;磷磷磷-磷联系可参与红毒反应,使其成为合成和有机金属化学中感兴趣的一个主题;此外,由于潜在的毒性和反应性能,在开发磷离心和合成其他含有磷的化合物时,还应用了磷离心法素,并由于其芳芳香的组群,四苯基磷还表现出严重的水恐惧特性,影响其在有机溶剂中的溶解性;在处理这一化合物时,应采取安全防范措施,因为许多有机磷化合物具有潜在的毒性和再活动性.

标题:通过钠选择性裂解c-P键从arcl制备有机膦的方法
摘要:研究了磷化钠r 2 Pna和其他碱金属磷化物r 2 Pm(m = Li和k)的制备,应用和反应机理.R 2 Pna可以通过sd(精细分散在矿物油中的钠)与次膦酸酯r 2 Por'和氯膦r 2 Pc1的反应准确而选择性地制备.R 2 Pna也可以通过选择性裂解c-p键由三芳基膦和二芳基膦制备.在这些反应中,Na优于li和k.R 2 Pna与多种arcl反应以有效产生r 2Par.Arcl优于arbr和ari,因为它们只会降低产品收率.另外,Ph 2 Pna优于ph 2 Pli和ph 2 Pk,因为ph 2 Pli不产生与phcl的偶联产物,而ph 2 Pk仅产生低产率的产物.Arcl苯环上的吸电子基团极大地促进了与r 2 Pna的反应,而烷基降低了反应活性.氯乙烯和烷基氯rc1也有效地反应.当t-Bucl没有产生相应的产物,金刚烷基卤化物可以高产率得到相应的膦.通过这种方法,由相应的氯化物制备了多种膦.还可以方便地从ph

摘要:The present invention describes a method for synthesis of relatively low molecular weight imprinted polymers using living polymerization, and their application in analytical chemistry, pharmacology, medicine and the food industry. Specifically the low-molecular weight polymers are synthesized by the polymerization of functional monomers in the presence of a template, such as a biological receptor, enzyme, nucleic acid, cell, virus, microorganism, tissue sample or drug using living initiator. The conditions of living polymerization ensure a relatively small size of synthesized molecules. Synthesized in this way molecules (dimers, oligomers, polymers, or their mixture) have a higher affinity to the template than the original monomers and can rebind it in vitro and/or in vivo. As a further aspect of the present invention, polymers synthesized as described above can be used as drugs in pharmacology and medicine, as receptor-specific ligands in analytical chemistry (sensors, assays), and for separations in the biotechnology, pharmaceutical and food industries.
