The potential for carbometallation reactions between organoberyllium and model alkenes and alkynes has been investigated in a computational study. Results indicate that barriers for carbometallation reactions between BeR and alkynes are as low as 100 kJ mol, and much lower than corresponding reactions with MgR. In contrast to carboboration reactions with BR, with organoberyllium 1,2-addition is favoured over 1,1-addition. It is concluded that carbometallation reactions with beryllium are likely feasible, and that the reaction between BePh and alkynes provides the best opportunity for the first experimental observation of carboberyllation.
在一项计算研究中，对有机铍与模型烯烃和炔烃之间的碳金属化反应潜力进行了研究。结果表明，BeR与炔烃之间的碳金属化反应势垒低至100 kJ/mol，远低于与MgR的相应反应。与BR的碳硼化反应不同，有机铍的1,2-加成比1,1-加成更有利。研究得出结论，铍的碳金属化反应可能是可行的，并且BePh与炔烃之间的反应为首次实验观察碳铍化提供了最佳机会。
