The present essay offers an overview of the latest developments in the chemistry of organoboron compounds. The unique structural characteristics and the versatile reactivity profile of organoboron compounds continue to expand their roles in several areas of chemistry. A growing number of boron-mediated reactions have become vital tools for synthetic chemistry, particularly in asymmetric synthesis, metal-catalyzed processes, acid catalysis, and multicomponent reactions. As a result, boronic acids and related molecules have now evolved as major players in synthetic and medicinal chemistry. Moreover, their remnant electrophilic reactivity, even under physiological conditions, has allowed their incorporation in a growing number of bioactive molecules, including bortezomib, a clinically approved anticancer agent. Finally, the sensitive and selective binding of boronic acids to diols and carbohydrates has led to the development of a growing number of novel chemosensors for the detection, quantification, and imaging of glucose and other carbohydrates. There is no doubt that the chemistry of organoboron compounds will continue to expand into new discoveries and new applications in several fields of science. Long History -Expanding RolesOrganic compounds containing boron have been known for over a century, and many aspects of their chemical properties and reactivity have been known for quite some time. Since the discovery and development of hydroboration, the resulting organoboranes are among the most widely used reagents and intermediates in organic synthesis including asymmetric reactions. Also, early investigations on the chemistry of boron hydrides and carboranes revealed new classes of compounds with unique structure and reactivity that continue to attract attention. Despite these early discoveries, however, the real potential of some of the more versatile and chemically stable organoboron compounds was not realized until recently.Indeed, the growing list of valuable organoboron compounds in addition to organoboranes [1] now includes organoboronic acids and boronates, [2] and more recently organotrifluoroborates.

“…Sodium benzenesulfinate produced the corresponding 2-phenylpyridine in 80% yield (Table 4, entry 11). It was noted that the 2-furyl, 3-pyridinyl and 4-indolyl sodium heteroaryl trifluoroborate were successfully reacted with 2-pyridinylsulfinate to afford heteroaryl-2-pyridine derivatives in 57%-73% yields (Table 4, entries [12][13][14].…”

“…Trifluoroborates are increasingly important reagents because of their favorable physical and chemical properties; additionally, they offer an alternative to toxic organometallic species such as organostannanes. [8][9][10][11][12][13][14][15] The tetracoordinate nature of the trifluoroborates makes them resistant to a variety of reaction conditions. This characteristic allows one to build complexity into a molecule while leaving the carbon−boron bond intact.…”

An efficient procedure for the synthesis of biaryls was catalyzed by Pd(CH 3 CN) 4 (BF 4 ) 2 is reported. This Pd-catalyzed cross-coupling reaction of aryltrifluoroborates with sodium arenesulfinates was developed under mild and environmentally benign conditions, in water without any ligand or additive. The reaction gave a range of structurally diverse unsymmetrical bi-aryl molecules with excellent yields, in which the byproduct was sulfur dioxide. It is worth noting that this protocol is also applicable to many heterocyclic aromatics such as thiophene, furan, pyridine, quinoline, isoquinoline and indole.
