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.
