摘要

We have discovered an unusual reaction sequence that interpolates the elements of ketene into a 1, 5-diene and forms a new seven-membered-ring ketone, as illustrated for 1, 5- cyclooctadiene (eq 1). Since we are unaware of any comparable sequence in the literature, our findings are reported here.
