A new stable germaphosphene, the 2,2-dimesityl-1-(2,4,6-triipropylphenyl)germaphosphene (1), has been made. It reacts quantitatively with benzaldehyde and α-phenyl-N-tert-butylnitrone to afford, by [2+2]- and [2+3]-cycoloadditions, respectively, the correponding four- and five-membered heterocycles 10 and 13. The conformations of these heterocycles are discussed. The reactions of 1 and 2,2-dimensityl-1-(2
制备了一种新的稳定的除磷膦,即2,2-二甲-1-(2,4,6-三丙基苯基)锗磷(1)。它与苯甲醛和α-苯基-N-叔丁基硝酮进行定量反应,分别通过[2 + 2]-和[2 + 3]-环转移,分别提供相应的四元和五元杂环10和13。讨论了这些杂环的构象。比较了1和2,2-二元-1-(2,4,6-三叔丁苯基)germ(2)与这些试剂的反应。
