Özet

Tin tetrakis(4-fluorophenyl) porphyrin, tin tetrakis(4-chlorophenyl) porphyrin and tin tetrakis(4-bromophenyl) porphyrin complexes were prepared by reaction of butyltin trichloride with tetrakis(4-fluorophenyl) porphyrin, tetrakis(4-chlorophenyl) porphyrin, and tetrakis(4-bromophenyl) porphyrin in tetrahydrofuran and toluene, respectively. These novel complexes were characterized by H-1, C-13 NMR, FTIR, mass spectroscopy and elemental analysis. The single site tin complex including fluoride was tested as a catalyst in polymerization of epsilon-caprolactone and was very effective. Polycaprolactone was characterized by H-1, C-13 NMR, and gel permeation chromatography.
