phosphine oxides and pyridinoids have been implemented and studied. Pyridine and isoquinoline react with propynenitrile and phosphine oxides at room temperature according to the N-vinylation/C-phosphorylation scheme to afford (Z)-N-(2-cyano-1-phenyl)ethenyl phosphoryl-1,4-dihydropyridines or -1,2-dihydroiso quinolines. In the case of pyridine on heating (80–85 °°°C), the reaction gives 4-phosphorylpyridines
已经实施和研究了 3-苯基-2-丙炔腈、仲氧化膦和吡啶之间的反应。根据N-乙烯基化/C-磷酸化方案,吡啶和异喹啉在室温下与丙炔腈和氧化膦反应,得到(Z)-N -(2-氰基-1-苯基) 乙烯基磷酰基-1,4-二氢吡啶或 - 1,2-二氢异喹啉。在加热(80-85°°C)吡啶的情况下,反应得到4-磷酰基吡啶(秒NH氩气 反应)和 3-苯基-丙烯腈低聚物。
