Abstract
Reaction of (5,10,15,20-tetraphenylporphinato)zirconium diacetate ((TPP)Zr(OAc)2) with organo-lithium or -magnesium compounds gave the corresponding σ-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.Keywords
