Abstract

Flash vacuum pyrolysis of the allyl ethers 9–11 and of the oxime ethers 15–17 at 650° C (5× 10–2–5× 10–3 Torr) generates 2-(aryliminomethyl) phenoxyl radicals 4 and 1-(2- aryloxyphenyl) alkaniminyl radicals 5 respectively which can interconvert via a spirodienyl radical leading to common products which are generally
