Webincorporation, the azide group,which is orthogonal to the glycan linkage, is then available for reaction with the phosphine group of the FLAG-phosphine conjugate. The azide-phosphine linkage is preferential, with no comparable functional groups inherent in cells or tissues that would compete with the reactive groups. WebSince functional groups on phosphorus substituents do not interfere in reduction with silanes, this phosphine synthetic method, via reduction of tertiary phosphine oxides with silanes, has most often been applied to the synthesis of chiral phosphine ligands (Equations (40) and (41)) < 79AG655, 91TA667, 92CL547 >.

WebOrganophosphine. Organophosphines are organophosphorus compounds with the formula PR n H 3−n, where R is an organic substituent. These compounds can be classified according to the value of n: primary phosphines ( n = 1), secondary phosphines ( n = 2), tertiary phosphines ( n = 3). All adopt pyramidal structures.
