  日期：——

  The reactions of carbon monoxide with nitrato(alkyl)mercury complexes HgRNO3(R = Bun, Me3C·CH2, and MeO·CH2·CH2) have been investigated in methanol. At low pressures (25 atm.) the main products were the esters RCO2Me and the nitro-compounds, RNO2. At higher pressures (200–300 atm.)α-oxo-esters, RCO·CO2Me, are also found. Nitrato(neopentyl)mercury was studied to allow a search to be made for rearranged

  一氧化碳与硝基（烷基）汞配合物HgRNO 3（R = Bu n，Me 3 C·CH 2和MeO·CH 2 ·CH 2）的反应已在甲醇中进行了研究。在低压（25个大气压）下，主要产物为酯RCO 2 Me和硝基化合物RNO 2。在较高压力（200–300大气压）下，α-氧代酯，RCO·CO 2我，也被发现。对硝基（新戊基）汞进行了研究，以寻找衍生自叔戊基（1,1-二甲基丙基）基团的重排产物。没有发现，并且可以得出结论，羰基化的机理不像这些复合物的溶剂分解那样涉及碳离子的形成。建议形成中间体羰基配合物。硝基（正丁基）汞与一氧化碳在水中反应，生成正戊酸，而在苯溶液中，硝基链烷和硝酸烷基酯与醇，酸和酯（ROH，RCO 2 H和RCO 2 R）一起形成可能是由于水的痕迹引起的。
