While the archetypal free phosphinidene, H‐P, has been studied for over a century, reports on uncomplexed, univalent phosphorus compounds are very sparse. Here we demonstrate production of HCCP in solid argon through the UV‐induced rearrangement and subsequent dehydrogenation of phosphapropyne, CH3CP. Migration of H atoms along the CCP backbone of CH3CP resulted in production of the previously unobserved
原型游离
次膦酸酯H-P的研究已经有一个多世纪的历史了,但有关未络合的一价
磷化合物的报道却很少。在这里,我们证明了通过UV诱导的重排以及随后的
磷丙炔CH 3 CP的脱氢,在固态
氩气中生产HCCP 。H原子沿着CH 3 CP的CCP主链迁移导致产生以前未被观察到的物质1-
磷丙二烯(CH 2 = C = PH),然后是
乙炔基膦(HCCPH 2)。
