  Diverse reactions of nitroxide-radical adducts of silylene, germylene, and stannylene

  摘要：

  The results of the thermolysis of 1:2 adducts of stable group-14 element divalent compounds [R(2)M:, R(2) = 1, 1 4,4-tetrakis(trimethylsilyl)butane-1.4-diyl; 1b, M = Ge; 1c, M = Sn] to TEMPO radical are discussed in detail. Whereas the thermal reactions of the 1:2 aducts [R(2)M(OR')(2), R' = 2,2,6,6-tetramethylpiperidin-N-yl; 3b, M - Ge; 3c, M = Sn] are understood to proceed by the initial homolysis of an M-O bond to give the corresponding aminoxy-substituted group-14 element radicals [R(2)(R'O)M(.); 2b, M = Ge; 2c, M = Sn] and TEMPO. the subsequent reactions of 2b and 2c were remarkably different to each other; 2b favors the N-O bond fission (path b) to give the corresponding germanone, while 2c prefers the M-O bond fission (path a) to give stannylene (1c). In combining with our previous results for aminoxysilyl radical (2a) [R(2)(R'O)Si], the origin of the remarkable differences in the reactivity among group-14 element radicals 2a-2c is discussed on the basis of the theoretical calculations for model reactions.Improved syntheses of the precursor dichlorogermane and dichlorostannane of germylene (1b) and stannylene (1c), respectively, are described in Section 3.

  The reactions of isolable dialkylgermylene 1 with benzoyl and substituted benzoyl chlorides afford the corresponding aroyl(chloro)germanes in high yields. While 2,2-dimethylpropanoyl chloride reacts similarly, the reactions of more reactive alkanoyl chlorides such as acetyl, propanoyl, and butanoyl chlorides give rather unexpectedly the corresponding dialkanoylgermanes 3 together with alkanoyl(chloro)germanes

  可分离的二烷基锗烯1与苯甲酰和取代的苯甲酰氯的反应以高收率提供了相应的芳酰基（氯）锗烷。尽管2,2-二甲基丙酰氯的反应类似，但更具反应性的烷酰氯（如乙酰基，丙酰和丁酰氯）的反应出乎意料地产生了相应的二烷酰锗烷3和烷酰（氯）锗烷2（2：3 = 4：1） 。芳酰基和链烷酰基（氯）锗烷2a – 2g和dikkanoylgermanes 3e – 3g通过多核NMR光谱，高分辨率质谱（HRMS）以及2a和3f的单晶X射线衍射研究对所得产物进行了充分表征。3e - 3g的紫外-可见光谱和对模型二酰基锗烷的TDDFT研究显示出两个分开的n→π*吸收带，表明分子中的两个羰基之间通过中心锗原子发生了显着的电子相互作用。
