已经实现了一种通过多炔环化在五元环中产生金属亚乙烯基结构的新型一锅反应。通过实验和计算分析了环状金属亚乙烯基配合物的环应变和高稳定性。稠环配合物中的金属亚乙烯基单元对亲核试剂和亲电试剂均不发生反应。然而，它在附近的羰基上发生反应，通过 DFT 计算研究了芳香族驱动过程中金属贡献因子的前所未有的转化。
A novel one-pot reaction producing a metal vinylidene structure in a five-membered ring by cyclization of a multiyne has been achieved. The ring strain and the high stability of the cyclic metal vinylidene complexes have been analyzed experimentally and computationally. The metal vinylidene unit in a fused-ring complex is unreactive to both nucleophiles and electrophiles. It reacts however at the nearby carbonyl group achieving the unprecedented conversion of metal tributing factors for the aromaticity-driven process has been studied by DFT calculations..
