Metathesis reaction
Web22 sep. 2024 · Olefin cross-metathesis is a cornerstone reaction in organic synthesis where stereoselectivity is typically governed by the structure of the catalyst. In this work, we show that merging Grubbs second generation catalyst, a classical E-selective catalyst, with a readily available photocatalyst, enables the ex 2024 Chemical Science HOT Article … WebIn organic chemistry, olefin–olefin metathesis of two unsaturated substrates for the formation of a new carbon–carbon bond has been widely explored and applied. Exploration of the construction of a carbon–carbon bond through the carbonyl–olefin metathesis reaction remains limited but has recently attracted significant interest and attention.
