Several 5,16-dialkyl(diaryl)-5,16-dihydro-5,16-diphospha-tetraepoxy[22]annulenes(2.1.2.1) 9 as possible precursors of aromatic 5,16-diphospha-tetraepoxy[22]annulenes(2.1.2.1) 8 are synthesized by cyclizing Wittig-reactions of the phosphane dialdehydes 15 with the bis-ylids of the phosphane-bisphosphoniumsalts 19.
几种5,16-二烷基(二芳基)-5,16-二氢-5,16-二磷-四环氧[22]环戊烯(2.1.2.1)9作为芳族5,16-二磷-四环氧[22]环戊烯的可能前体( 2.1.2.1)8是通过使膦二醛15的Wittig反应与膦-双盐19的双-羟基环化而合成的。
