racemic cyclobutanes (1RS,2RS,1'SR)-1-(1-methoxyethyl)-2-vinylcyclobutane (16b) and (1SR,2SR,1'SR)-1-(1-methoxyethyl)-2-vinylcyclobutane (17b) each undergo a sigmatropic hydrogen shift (reverse enereaction) amounting to about 18% of the total pyrolysis product, in addition to four other unimolecular processes
