Organoboron reagents

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.
