It has been shown, on the basis of the analysis of CIDNP effects, that allene and (Me3Si)2NH — major products of the photoinduced reaction of Et3SnCH2CHCH2 and (Me3Si)2NBr — result from a radical pair comprised of CH2CHBrCH2SnEt3 and N(SiMe3)2 free radicals. Allene is formed through the β-cleavage of the short-lived homolytic substitution product Et3SnCH2CBrCH2.
已经示出,的CIDNP影响的分析的基础上,即丙二烯和(ME 3 Si)的2 NH - ET的光致反应的主要产物3 SNCH 2 CHCH 2和(ME 3 Si)的2 NBR -由CH 2 CHBrCH 2 SnEt 3和N(SiMe 3)2自由基组成的自由基对产生。丙二烯通过短暂的均裂取代产物的Et的β裂解而形成的3 SNCH 2 CBrCH 2。
