Santelli

Bertrand and Santelli (89) have investigated the hydrolysis, under apparently heterogeneous conditions, of 4,5-hexadien-2-yl tosylate, 114, and 4-methyl4,5-hexadien-2-yl tosylate, 115. After 90 min at 80°, 114 upon steam distillation yields a mixture consisting of 3% hydrocarbon 67% of cis- and rrans-2-methylcyclopropyl methyl ketone, 116 and 30% of 4,5-hexadien-2-ol, 117. When optically active 114 was treated under similar conditions, the resulting rrans-2-methylcyclopropyl methyl ketone had an inverted configuration at the reaction center, whereas the dienol 117 was found to be racemic (90). This... 

A good correlation was found between the fraction of cyclized or rearranged products and the extent of participation k /kg. Similar results were observed by Santelli and Bertrand (92) on essentially the same systems. Jacobs and Macomber (91) as well as Santelli and Bertrand (92) suggest a bicyclo-butonium ion 125 as the first formed intermediate (with the predominance of...
