Efficient Ruthenium Carbenoid-Catalyzed Cross-Metathesis of Allyl Halides with Olefins

Abstract: [reaction: see text] Cross-metatheses of allyl halides and terminal olefins mediated by catalyst 2 are reported and showed good yield and excellent E/Z selectivity. The application of these compounds as alkylating reagents is also demonstrated.

“…(Roy and co-workers have also been able to demonstrate the compatibility of both 6 and 3 with allyl halides in CM couplings. [22] ) Lovely and Seshadri [23] were able to effect CM reactions between olefinic ferrocene derivatives [24] and methyl acrylate, albeit with a very high catalyst loading (20 %). It is clear that more reports are needed before this contentious issue can be resolved.…”

“…[20] Ob 6 mit konjugierten elektronenarmen Olefinen verträglich ist, wird gegenwärtig diskutiert. Die wenigen verfüg-baren Daten zu dieser möglicherweise wichtigen Reaktion weisen eher auf eine Unverträglichkeit hin; allerdings wurden [22] Lovely und Seshadri [23] gelang die Umsetzung von olefinischen Ferrocenderivaten [24] mit Methylacrylaten, wobei allerdings große Katalysatormengen (20 %) benötigt wurden. Es steht außer Zweifel, dass zur Beilegung dieser Kontroverse weitaus mehr Ergebnisse nötig sind.…”

“…The example of CM between allylbenzene, a type I olefin, and allyl bromide, promoted by Gru-I, was published by Castedo et al (Scheme 12). 31 Further improvements in terms of yield were made by using the more active Gru-II, 32,33 Hov-II, 34 and finally Est-II 35 catalysts. It was noted that the internal alkene 39 can act as a convenient replacement for the more volatile allyl chloride.…”
