Previous studies have led to the conclusion that a large majority of acyclic 1,4-dienes do not undergo photochemical di-π-methane (DPM) rearrangement under triplet-sensitized irradiation. The results of a detailed analysis of these processes demonstrate that a series of these compounds do indeed undergo highly efficient DPM rearrangement from their triplet excited states when suitable triplet sensitizers are used.
