PREPARATION OF SOME 2,4,6-CYCLOHEPTATRIENE-1-YL KETONES. STRONG PREFERENCE FOR THE NORCARADIENE ISOMER IN THE CASE OF THE 2,4,6-CYCLOHEPTATRIENE-1-YL t-BUTYL KETONE

t-Butyl, i-propyl and phenyl 2,4,6-cycloheptatriene-1-yl ketone (1a,c,d, respectively) have been synthesized.At -139 deg C, rather unexpectedly, the t-butyl ketone 1a exists in a 1:1 equilibrium with its norcaradiene isomer 2a.

Syntheses of 2,4,6-Cycloheptatrien-1-yl Ketones

The phenyl(trimethylsiloxy)acetonitriles 5a - g, prepared by umpolung reactions with trimethylsiloxy cyanide, reacted after deprotonation with the tropylium cation 6 to give the 2,4,6-cycloheptatrien-1-ylaryl(trimethylsiloxy)acetonitriles 7a - g.After cle

FACILE SYNTHESES OF 2,4,6-CYCLOHEPTATRIENYL KETONES

The synthesis of the 2,4,6-cycloheptatrienyl ketones 1a-1e by two alternative routes is reported: Route 1): The adducts 3a-c from the phenyl(trimethylsiloxy)-acetonitriles 2a-c, known as "umpolung" reagents, and tropylium tetrafluoroborate are cleaved by
