- We have already reported that the unusual nucleophilic substitutions: R-OH + Cl−→ - R-Cl and Ph-C(O)Br + Cl−→ Ph-C(O)Cl are catalized by titanium ion that assists the departure of the hydroxylic oxygen and the bromide ion to which is already bonded or coordinated: (a) See Ref. 2c; (b) Clerici, A. and Porta, O., Tetrahedron Lett., 1987, 28, 1541

- The physical data were obtained as follows: melting points in a Koffler apparatus (uncorrected), IR spectra on a Perkin-elmer E 177, Mass spectra on a Hitachi-Perkin-Elmer RMU 6D at 70 eV, 1H NMR spectra on a Varian EM-390 (90 MHz) with Me4Si as an internal standard. Elemental analysis of the products was satisfactory.
