Preparation of Novel ?-Bonded Organozirconium(IV) Porphyrins and Photoreduction to the Zirconium(II) Complex by Visible Light

Article abstract of DOI:10.1246/cl.1992.1173

Reaction of (5, 10, 15, 20-tetraphenylporphinato)zirconium diacetate ((TPP)Zr(OAc)2) with organo-lithium or -magnesium compounds gave the corresponding ?-bonded organozirconium(IV) porphyrins ((TPP)ZrR2, R = Me, Et, n-Bu, and Ph).Irradiation of (TPP)ZrMe2 with visible light resulted in a clean generation of the low-valent zirconium(II) porphyrin complex.
