Unusual Metalloporphyrins. Synthesis and Properties of a Dimetallic Boron Porphyrin Complex.

摘要

Reaction of BC13 acetonitrile adduct with tetraphenylporphine affords the corresponding chloro-boron complex. Chromatography of this chelate on alumina results in ligand exchange producing an unusual tetrahydroxydiboron porphyrin. This complex is characterized by visible, ir, nmr, and mass spectrometry, as well as elemental analysis. The diboron derivatives are easily demetallated in solution and are formulated as having out of place structures. (Author)
