Solutions of salicyclic, ascorbic, and citric acids were reacted with boric acid, followed by NaH 2 PO 4 . The products, triphosphateborate ester of salicylic acid ( 1 ), orthosphateborate ester of ascorbic acid ( 2 ), triphosphateborate ester of ascorbic acid ( 3 ), and orthosphateborate ester of citric acid ( 4 ), were ash precipitated with cold acetone and characterised by microanalysis, thermal analysis, FT-IR, Raman, 11 B NMR, 31 P MAS NMR, and mass spectroscopic techniques. Analytical results indicated the presence of {C{O{B{O{P{ linkages with the attached phosphate groups varying between orthophosphate and triphosphate, depending on the starting material. The biomolecules studied in this work may serve as models in the B{P-organic system and the results would provide a possible contribution to boron prebiotic chemistr
