The distributions shown in Figure for the trans-1-propenyl intermediates gave k rot /k clos = 71.4 while the distributions for the cis-1-propenyl intermediates gave k rot /k clos = -25.5, clearly an impossible situation, which is caused by the result noted above that more cis product is formed from the trans olefin than is formed from the cis olefin. Thus, a problem exists in some aspect of these reactions, possibly product identification and/or product distributions analysis.
