Although, olefin metathesis has been applied in the industrial conversion o
f non-functionalized alkenes for several decades, only the development of n
ovel catalysts during the lost decode has widened the scope of the reaction
in a way that it now belongs to the standard repertoire of synthetic organ
ic chemistry. The recent success in the development of tailored catalysts i
ndicates, that the full potential of olefin metathesis as a synthetic metho
d still remaines to be uncovered.
