可分离的二烷基亚锡与1-金刚酰基、2,2-二甲基丙酰基、苯甲酰基和取代的苯甲酰氯反应，以良好的收率得到相应的酰基（氯）锡烷。与更具反应性的乙酰基和丙酰氯的类似反应不会产生相应的插入产物，而是通过过度反应产生相应的二氯锡烷。苯甲酰（氯）锡烷与乙酰氯反应定量得到相应的1,2-二酮和二氯锡烷。所获得的酰基（氯）锡烷通过多核核磁共振波谱、高分辨率质谱和单晶 X 射线衍射研究进行了充分表征。
The reactions of isolable dialkylstannylene1with 1-adamantanoyl, 2,2-dimethylpropanoyl, benzoyl, and substituted benzoyl chlorides afford the corresponding acyl(chloro)stannanes in good yields. Similar reactions with more reactive acetyl and propanoyl chlorides do not give the corresponding insertion products but the corresponding dichlorostannane by the overreaction. The benzoyl(chloro)stannane reacts with acetyl chloride to afford the corresponding 1,2-dione and the dichlorostannane quantitatively. Acyl(chloro)stannanes obtained were fully characterized by multinuclear NMR spectroscopy, high-resolution mass spectrometry, and by single-crystal X-ray diffraction studies.
