Migratory insertion of alkenes into metal-oxygen and metal-nitrogen bonds.

چکیده
The insertion of an unsaturated ligand into a M-C or M-H bond proceeds through migratory insertion, a fundamental organometallic reaction. Recent literature documents evidence of the migratory insertion of alkenes into an M-O and M-N bonds for alkene alkoxylation and alkene amination reactions, respectively. Herein we provide an overview of the literature and a perspective on how these recent experiments relate to classic experiments on C-O and C-N bond formation with alkene complexes of the late transition metals.

Synthesis of [RuCl2(NO)2(THF)] and its double C-N bond-forming reactions with alkenes.
While the activation of relatively inert gases such as N2 and CO with organometallic complexes remains a topic of intense investigation, methods for controlling the reactivity of nitric oxide at transition-metal centers have received considerably less attention. For example, the migratory insertion of NO into metal–alkyl or metal–aryl bonds has been observed in only a handful of metal complexes...
متن کاملMigratory Insertion of Carbenes into Au(III)–C Bonds
Migratory insertion of carbon-based species into transition-metal-carbon bonds is a mechanistic manifold of vast significance: it underlies the Fischer-Tropsch process, Mizoroki-Heck reaction, Ziegler-Natta and analogous late-transition-metal-catalyzed olefin polymerizations, and a number of carbonylative methods for the synthesis of ketones and esters, among others. Although this type of react...

Dinuclear mu-oxo osmium porphyrins containing terminal Os=CPh2 bonds with a linear C=Os-O-Os=C moiety were prepared, which are reactive toward pyridine to form [Os(Por)(CPh2)(py)] and are active catalysts for inter- and intra-molecular cyclopropanation of alkenes and for carbene insertion into saturated C-H bonds.
متن کاملEnantioselective Narasaka-Heck cyclizations: synthesis of tetrasubstituted nitrogen-bearing stereocenters.
The first examples of highly enantioselective Narasaka-Heck cyclizations are described. A SPINOL-derived P,N-ligand system enables Pd-catalyzed 5-exo cyclization of a range of oxime esters with sterically diverse trisubstituted alkenes to generate dihydropyrroles containing tetrasubstituted nitrogen-bearing stereocenters in 56 to 86% yield and 90 : 10 to 95 : 5 e.r. These processes are rare exa...
متن کاملTransition metal catalyzed element–element additions to alkynes
The efficient and stereoselective synthesis of, or precursors to, multi-substituted alkenes has attracted substantial interest due to their existence in various industrially and biologically important compounds. One of the most atom economical routes to such alkenes is the transition metal catalyzed hetero element–element0 p-insertion into alkynes. This article provides a thorough up-to-date re...
