Low valent organoelement hydrides of tin and lead, [(ArSnH)] and [(ArPbH)], were reacted with diorganocarbodiimide and adamantylisocyanate to give products of hydroelementation reactions. Carbon dioxide also reacts with both low valent hydrides, but a reaction product was only characterized in the tin hydride case. A hydride was transferred to the carbon atom and the formed formate anion [HCO] shows coordination at two tin atoms. Carbon disulfide reacts with the stannyl-stannylene isomer of the low valent organotin hydride. The stannyl part forms a Sn-C bond whereas the stannylene moiety coordinates at the two sulfur atoms. The dimeric organolead hydride exhibits transfer of both hydride ligands to the carbon atom of CS to give a dithiol ligand [CHS] bridging both organolead units.
低价锡和铅的有机元素氢化物[(ArSnH)]和[(ArPbH)]与二有机碳二亚胺和金刚烷基异氰酸酯反应，生成氢化元素反应的产物。二氧化碳也能与这两种低价氢化物反应，但仅在氢化锡的情况下对反应产物进行了表征。一个氢化物转移到碳原子上，形成的甲酸根阴离子[HCO]在两个锡原子处显示配位。二硫化碳与低价有机锡氢化物的亚锡-亚锡烯异构体反应。亚锡部分形成一个Sn-C键，而亚锡烯部分在两个硫原子处配位。二聚有机铅氢化物将两个氢化物配体都转移到CS的碳原子上，生成一个桥连两个有机铅单元的二硫醇配体[CHS]。
