“…To the best of our knowledge, the synthesis of diarylmethanols using aryltriolborates as coupling partners has very few reports to date [ 32 ], even though aryltriolborates have exceptionally high levels of stability in air/water, reasonable solubility in organic solvents, and are generally used as the aryl source for C-C and C-N bond-forming reactions [ 38 , 39 , 40 , 41 , 42 , 43 ]. As part of the continuing efforts in our laboratory toward the development of palladium-catalyzed addition reactions [ 33 , 34 , 35 , 36 , 37 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 ], we herein report a simple and efficient protocol for the synthesis of diarylmethanols by the Pd-catalyzed base-free addition of aryltriolborates to aldehydes ( Scheme 1 ).…”
