Cited by: The book also considers classical and novel ylide systems in organometallic chemistry, including phosphorinanium and phospholanium ylides and organometallic compounds of double ylides. The reaction of the triplet carbene with olefins gives cyclopropane derivatives in a nonstereospecific way and is accompanied by hydrogen abstraction, because the triplet.
As the syntheses of cyclopropane derivatives can be accomplished by several highly efficient procedures, these derivatives have emerged as important intermediates for the construction of.
[25–28]) (eqn ) convert alkenes into cyclopropane derivatives. Nowadays, useful asymmetric versions of these reactions exist, either using chiral auxiliaries or employing chiral catalysis. An alternative catalytic strategy for the preparation of benzylmethacrylate esters, key intermediates in the synthesis of coenzyme Q10 and derivatives, was reported.
