Abstract
The hydrolytic cleavage of dypnone (3) to benzoic acid (A-cleavage reaction) catalyzed by BFs was found to be promoted considerably by the addition of inorga nic acids. Moreover the condensation of (3) was suppressed t o some extent by the addition of 85% H3POi.Difference in activities of BF3 85% HsPOs complexes and BFg, water complexes for A-cleavage reaction was examined. The rate oHormation of (1) cafalyzed with BF3, 85%H4PO4(BF/(H3PO4+H20)=1(mol/mol)) was about three times faster than with BF3, H20. The former complex was more stable for heat. The order of activity for A-cleavage reaction was as follows;BFs, 8596 HgPOb BFs, H20 BFs 2(85% HgPO4) BF3, 2H20.
