Abstract

A new rhodium complex [Rh(cod)(TTT)₂] was synthesized by [Rh(cod)Cl]₂ as a precursor, and 4,4',4''-(1,3,5-triazine-2,4,6-triyl)trianiline (TTT) as a ligand. Its structure was verified by ¹H and ¹³C NMR. The results indicate that the complex shows high activity in phenylacetylene polymerization. It was applied to the polymerization of phenylacetylene with a yield of 45.0% and Mw = 2.26×10⁵ at ultra-low rhodium feed ratio ([Rh.]/[M.]=1/60000).

Graphical abstract

A new rhodium complex [Rh(cod)(TTT)₂] was synthesized by [Rh(cod)Cl]₂ as a precursor, and 4,4',4''-(1,3,5-triazine-2,4,6-triyl)trianiline (TTT) as a ligand. It was applied to the polymerization of phenylacetylene with a yield of 45.0% and Mw = 2.26×10⁵ at ultra-low rhodium feed ratio ([Rh.]/[M.]=1/60000

含氨基配体的铑催化剂[Rh(cod)(TTT)2]的合成及其在苯乙炔聚合中的催化性能

以[Rh(cod)Cl]2 为前体，4,4',4''-(1,3,5-三嗪-2,4,6-三基)三苯胺（TTT）为配体，合成了一种新的铑配合物[Rh(cod)(TTT)2]。通过 1H 和 13C NMR 验证了其结构。结果表明，该配合物在苯乙炔聚合中表现出很高的活性。在超低铑进料比（[Rh.]/[M.]=1/60000）条件下，该配合物用于苯乙炔的聚合，产率为 45.0%，Mw = 2.26×105。图解摘要以[Rh(cod)Cl]2 为前驱体，4,4',4''-(1,3,5-三嗪-2,4,6-三基)三苯胺 (TTT) 为配体，合成了一种新的铑配合物[Rh(cod)(TTT)2]。它被用于苯乙炔的聚合，在超低铑进料比（[Rh.]/[M.]=1/60000）条件下，产率为 45.0%，Mw = 2.26×105

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
