WebTo understand the cross-metathesis product, it was necessary to label the alkanes taking part in the cross-metathesis reaction. During the cross-metathesis reaction of propane and n-decane, propane was chosen to be labeled.172 The idea to select 13 C labeled propane was to distinguish cross-metathesis products from homo metathesis products. Webthe olefin metathesis mechanism. 6 ROBERT GRUBBS In the late 1980s, a series of tungsten carbenes had been produced by the groups of Jean- ...
