[Ir(COD)Cl]2/tris(2,4-di-t-butylphenyl)phosphite-catalyzed addition reactions of arylboronic acids with aldehydes were described. The Ir(I) catalyst, generated from [Ir(COD)Cl]2 and tris(2,4-di-t-butylphenyl)phosphite, was an efficient catalyst system for the addition reactions of a variety of arylboronic acids with aromatic and aliphatic aldehydes. The easy availability of the catalyst and good yields make these reactions potentially useful in organic synthesis.

A highly crystalline porous Ni(HBTC)BPY was synthesized from the reaction of 1,3,5-benzenetricarboxylic acid, nickel nitrate hexahydrate, and 4,4′-bipyridine by a solvothermal method. Physical characterizations of the solid catalyst were achieved by using several techniques, including X-ray powder diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR), atomic absorption spectrophotometry (AAS), and nitrogen physisorption measurements. The Ni(HBTC)BPY exhibited high catalytic activity in the arylation of aldehydes with arylboronic acids to form diarylmethanols. The catalyst could be separated from the reaction mixture by simple filtration or centrifugation, and could be reused without a significant degradation in catalytic activity. No contribution from homogeneous catalysis of active species leaching into the liquid phase was detected.

experimental part, p. 7602 - 7607 (2011/11/12)
CuCl/bipyridine-catalyzed addition reactions of arylboroxines with aldehydes and α,β-unsaturated ketones at elevated temperatures were described. By using the microwave energy, CuCl/bipyridine-catalyzed addition reactions of arylboroxines with aldimines were also realized.

experimental part, p. 1677 - 1679 (2011/04/25)
Applying sealed vessel microwave heating at 180 °C in toluene the arylation of aromatic and aliphatic aldehydes with arylboronic acids using 1-2 mol % of Ni(acac)2 as a catalyst can be performed efficiently within 10-30 min providing the desired diarylmethanols or benzyl alcohols in good yields.
Carbinol derivatives via rhodium-catalyzed addition of potassium trifluoro(organo)borates to aldehydes
Pucheault, Mathieu,Darses, Sylvain,Genet, Jean-Pierre
, p. 4714 - 4716 (2007/10/03)
Reaction of potassium aryltrifluoroborates with aldehydes, in the presence of a rhodium catalyst, afforded carbinol derivatives in high yields under mild aqueous conditions; this efficient reaction proved to be general, allowing the production of highly hindered diarylmethanols and aliphatic aldehydes were also reactive under these conditions.
