Abstract The title compounds are difunctionalized acetylenic building blocks, which can serve as electrophilic dienophiles and dipolarophiles in [4+2] and azide-iodoalkyne [3+2] cycloaddition reactions, which, however, require strong thermal activation. In their crystal structures, they are self-complementary tectons, which are arranged in polymeric chains maintained by very short intermolecular Csp–I···O=P halogen bonds.

（碘乙炔基）膦酸二乙酯和（碘乙炔基）二苯基氧化膦：晶体结构和一些环加成反应

摘要 标题化合物是双官能化的炔基结构单元，可在 [4+2] 和叠氮化物-碘炔 [3+2] 环加成反应中作为亲电二烯体和偶极体，但需要强烈的热活化。在它们的晶体结构中，它们是自互补构造，它们排列在聚合物链中，由非常短的分子间 Csp–I...O=P 卤素键维持。
