TRANSITION METAL-PROMOTED REACTIONS. VII. NOVEL REACTIONS OF ACID CHLORIDES WITH PENTACARBONYLIRON IN AROMATIC SOLVENTS

Upon treatment with Fe(CO)5 in an aromatic hydrocarbon solvent aromatic acid chlorides gave a mixture of triarylmethane and tetraarylethane.The reaction may proceed via benzaldehyde and diarylmethanol intermediates.A free radical mechanism is proposed.

Conformational control of photoreactivity: Three α-mesityl ketones that undergo efficient radical cleavage

α-Mesitylisobutyropohenone, 1,2-dimesitylethanone, and 2-phenyl-1,2-dimesitylethanone all undergo only one photoreaction in solution, α-cleavage to acyl radicals. Quantum yields are all over 0.30 and triplet rate constants are ≥5 x 108 s-1. In each case, bond rotations are so slow that reaction occurs from the preferred ground state geometries, which hold the molecules in conformations ideal for cleavage. The large cleavage rate constants reflect relief of steric strin as well as ideal orientation of π and σ orbitals.
