Abstract
The coordination chemistry of a phospha-macrocycle meso-cis-2,10-diphenyl-6-aza-2,10-diphenylphabicyclo[9.40]pentadeca-11(1),12,14-triene (11-P2NH) with (η5-cyclopentadienyl)dicarbonyliodoiron and (η5-pentamethylcyclopentadienyl)dicarbonyliodoiron was investigated. Thus 11-P2NH reacts with CpFe(CO)2I in benzene under photochemical conditions to yield a mixture of [P,P′,N-(11-P2NH)FeCp]I (2) and [P,P′-(11-P2NH)Fe(CO)Cp]I (3). Conversion of 3 into 2 was achieved by photochemical treatment of 3 in acetonitrile. The amine donor of the macrocycle in 2 was slowly transformed into a coordinating imine moiety. Similar behaviour was observed for the pentamethylcyclopentadienyl analogue. The crystal structure of [P,P′,N-(11-P2NH)FeCp{black star}]I is determined. © 1994.
