Abstract
Two reaction paths, leading from formaldehyde 1 and ketene 2 to 2-oxet anone 3, are examined. Mechanism A, involving the initial formation of the C2-O3 bond, a stepwise mechanism with biradical character, is fou nd to be more favoured than mechanism B, a concerted, but highly-async hronous mechanism with zwitterionic character involving the initial fo rmation of the C4-C5 bond.
