Carboxylic acids are readily reduced to the corresponding aldehydes in high yields by treatment of acyloxy-9-borabicycloC3.3.llnonanes with lithium 9-boratabicycloL3.3.l]nonane (Li 9-BBNH) at room temperature. Thexylchloroborane-methyl sulfide 2 and thexylbromoborane-methyl sulfide 3
The 1:1 complex between the zwitterionic piperidinium-3-carboxylate (P3C) and salicylic acid (SAL), P3CΓSAL, has been characterized by single crystal X-ray analysis, FTIR and NMR spectroscopy, and by DFT calculations. The crystals are orthorhombic, space group Pbca, with a = 11.6477( 7), b = 9.1754(
