Condensation of o-phenylenediamine and phthalaldehyde using molybdenum(0) as template. Isolation and crystal and molecular structure of an intermediate molybdenum complex with an η2-bonded aldehydic group

Abstract

Reaction of [Mo(CO)₃(C₆H₅Me)] with o-phenylenediamine and phthalaldehyde carried out in methanol at room temperature gives [Mo(CO)₃L]{L = 2-[(2′-aminophenyl)iminomethyl]benzaldehydea. The molecular structure determination of [Mo(CO)₃L] shows the open-chain nature of L together with the η²-co-ordination of the aldehydic group to the metal. The compound is an openchain intermediate for a N₄ macrocyclic complex.
