Ya, the Mo catalyst is a slight modification of previously disclosed examples. It says it works better with Mo because Ru complexes are generally deactivated by halogen-substituted alkenes. From a synthesis standpoint, thought the cross-metathesis method is a good complementary to existing methods of making alkenyl halides. Will be interesting if trans-isomers could be synthesized too.

A recent article on making alkenyl halides stereoselectively using olefin metathesis: http://www.nature.com/nature/journal/v531/n7595/full/nature17396.html Seems a decent alternative way of generating such compounds, especially fluorides. What do you guys think?
