An alpha,beta-(C-C-C) agostic bond is found to provide the additional stabilization needed to make the formally 14-electron metallacyclobutane intermediate lower in energy than its 16-electron alkylidene analogue during olefin metathesis catalysis.
研究发现，在烯烃复分解催化过程中，α,β-(C-C-C) 螯合键提供了额外的稳定性，使得形式上具有14个电子的金属环丁烷中间体的能量低于其具有16个电子的亚烷基类似物。
