A condensation of phenyl- or l-menthylphosphine with formaldehyde and 4,4´-bis-(4´-aminophenoxy)biphenyl proceeding as a covalent self-assembly gave rise to the first representatives of 46-membered P,N,O-containing cyclophanes, namely, 13,17,83,87-tetra-R-3,6,10,13-tetraoxa-1,8(1,5)-di(1,5-diaza-3,7-diphosphacyclooctana)-2,4,5,7,9,11,12,14(1,4)-octabenzenacyclotetradecaphanes (R = Ph (1), l-Ment (2))
苯基或 l-薄荷基膦与甲醛和 4,4'-双-(4'-氨基苯氧基)联苯的缩合反应作为共价自组装产生了 46 元含 P,N,O 的第一个代表环芳烃,即 13,17,83,87-tetra-R-3,6,10,13-tetraoxa-1,8(1,5)-di(1,5-diaza-3,7-diphosphacyclooctana)- 2,4,5,7,9,11,12,14(1,4)-八苯并环十四烷(R = Ph (1), l-Ment (2))。笼型大环四膦 2 与(环辛二烯)二氯铂(ii)和-钯(ii)以及(四氢呋喃)五羰基钨(0)反应形成双核配合物,其中金属原子配位为 1,5 -diaza-3,7-diphosphacyclooctane 片段通过 P,P-螯合模式。
