Witryna5 paź 2024 · 1 Introduction. Organoboron reagents are among the most widely used families of compounds in catalysis and organic synthesis. 1 Reactions involving organoboronic compounds usually benefit from a high functional-group tolerance and these reagents generally prove to be non-toxic. Classically, they have been exploited … Witryna17 maj 2013 · Organotrifluoroborates are partners for cross-coupling that have emerged as complementary and often unique alternatives to other organoboron reagents. This chapter provides a comprehensive overview of all cross-coupling reactions of the various classes of organotrifluoroborates that have been carried out through August, 2009.

Witryna18 lip 2024 · The direct coupling of allylic alcohols with arylboronic acids or their derivatives catalyzed by Ni(cod) 2 in the presence of a catalytic amount of base has been developed. A wide variety of allylic substrates or arylboronic acids turned out to be applicable to this catalytic system. WitrynaThis review covers new trends towards the selective synthesis of organoboron compounds where boron reagents and cyclic substrates participate in the generation of carbanions, in the presence of stoichiometric amounts of main-group metals or catalytic amounts of transition metal complexes, via ring opening coupling transformations. … Witryna19 paź 2011 · Organotrifluoroborates: Organoboron Reagents for the Twenty-First Century.
