1. A method of making an organoboron compound, comprising a reaction described by one of the following schemes:wherein X1 is O, N, S, or C, wherein each of R, R1, R2, R3, R4, and R5 are independently selected from: H, a carbonyl functional group, a carbocycle group, a heterocycle, a halide, or an alkyl group, wherein, optionally, R1 and R2 together with the carbon atoms they are attached to form a cyclic moiety, wherein X2 is catecholate, pinacolate, ethylene glycolate, 1,3-propanediolate, N-methyliminodiacetate, 2,2′-azanediyldiethanolate, fluoride, or chloride, wherein n is 0 to 8, wherein y is from 1 to 3, wherein X3 is C, O, N, or S, and wherein X4 is a halogen, trifluoroacetic acid (TFA), tosylate (OTs), mesylate (OMs), or triflate (OTf);
wherein the reagent in each Scheme (1) to (25) is reacted with a salt of BX2 and a Lewis acid metal catalyst to form the organoboron compound(s) shown in each Scheme (1) to (25). |
