Abstract
Unprecedented E/Z isomerisation of a Si![[double bond, length as m-dash]](https://www.rsc.org/images/entities/char_e001.gif)
P bond was observed by temperature dependent NMR spectroscopy. DFT calculations showed that the coordination of phosphasilene to tungsten lowered the rotational barrier from 19.1 to 14.2 kcal mol?1. The thermodynamically more stable phosphinosilylene tungsten complex is formed at elevated temperatures through substituent migration.
