diyne. This has demonstrated the donor ability of the diiodobutadiyne that was previously known to act as a π-acceptor through the Lewis acidic iodine atoms. This work has expanded the temperature limits of the solvent-free synthesis strategy for potential study of thermally unstable species.
在升华-沉积反应中,使用丙酮单加合物[Rh 2(O 2 CCF 3)4 ·(OCMe 2)]代替未连接的四(三氟乙酸)二氢吡啶鎓(II),可以研究热敏性1, 4-二碘-1,3-丁二炔。一种新的混合配体有机金属化合物,[Rh 2(O 2 CCF 3)4 ·(OCMe 2)] 2 ·(C 4 I 2),已经以晶体形式分离出来,并通过X射线衍射研究表明其具有η 2(1,2):η 2二炔的(3,4)-桥接模式。这证明了以前已知通过路易斯酸性碘原子充当π-受体的二碘丁二炔的供体能力。这项工作扩大了无溶剂合成策略的温度范围,可用于热不稳定物质的潜在研究。
