scaffold for the syntheses of inorganic–organic-based hybrid cyclotriphosphazenes, as it is a highly robust skeleton among inorganic phosphorus–nitrogen ring systems. However, hybrid cyclotriphosphazenes with pendant arm(s) have been quite less explored. In the present study, the unsymmetrical bulky 4-methoxybenzyldiamines, CH3OPhCH2NH(CH2)nNHR (n = 0, R=CH3 2; n = 0, R = C2H5 3 and n = 1, R = CH3 4)
摘要 六氯环三磷腈的 N 3 P 3环,N 3 P 3 Cl 6 ( 1 ) (HCCP;三聚体),被广泛用作合成无机-有机杂化环三磷腈的支架,因为它是一种非常坚固的骨架无机磷-氮环系统。然而,对带有悬臂的杂化环三磷腈的探索较少。在本研究中,不对称庞大的 4-甲氧基苄基二胺CH 3 OPhCH 2 NH(CH 2 ) n NHR ( n = 0, R=CH 3 2 ; n = 0, R = C 2H 5 3和n = 1,R = CH 3 4 ),是在将脂肪族二胺与4-甲氧基苯甲醛缩合反应形成的相应席夫碱还原后获得的。二胺 ( 2 – 4 ) 与 HCCP ( 1 ) 的反应产生了新的单螺-( 5 – 7 )、顺式-二螺 ( 8 – 10 ) 和反式双螺 ( 11 – 13 ) 环三磷腈与 4-甲氧基苄基 (p-茴香基)悬垂臂。完全取代的单螺衍生物;5a – 7a , 5b-图7b和图5c
