o-Phenylenebis(phenylphosphine)(II), now readily available, is a valuable precursor in the synthesis of several new heterocyclic systems having a benzene ring fused to a five- or six-membered ring containing at least two phosphorus atoms. The following heterocyclic systems (with phenyl substituents) have been prepared: the 1,2,3-benzotriphospholes (V; R = Me or Et); the 1,3,2-benzodiphospharsoles (VIII;
现已很容易获得的邻苯二甲双(苯基膦)(II)是几种新的杂环体系的合成中有价值的前体,这些杂环体系的苯环与含至少两个磷原子的五元或六元环稠合。已经制备了下列杂环系统(具有苯基取代基):1,2,3-苯并三磷(V; R = Me或Et);1,3,2-苯并二磷基(VIII; R = Ph或Me); 1,3-苯并二磷(X); 1,4-苯并二膦酸酯(XI)和(XXVII); 和二苯并[ c,g ] [1,2,5,6]-四磷霉素(XXIII)。已经研究了这些化合物的化学和光谱性质。
