A concise synthesis of acylborons was achieved by ozonolysis of alkenyl MIDA (N-methyliminodiacetic acid) boronates. This reaction exhibits excellent functional-group tolerance and is applicable to various acyl MIDA boronates and potassium acyltriflurobor

The synthesis of thioamides via the condensation reaction of thiocarboxylic acids with amines is described. Using 3-cyano-1,2,4-triazole as a favorable nucleophilic catalyst and 3-cyano-1,2,4-triazol-1-yl-tris(pyrrolidine-1-yl)phosphonium hexafluorophosphate (PyCTP) as a new phosphonium-type condensing reagent, thioamides are obtained selectively over amides, which can be attributed to the hardness of the phosphorus center of the condensing reagent.
