Conversion of ketone trimethylsilylcyanohydrins to several types of compounds

Cyclic ketone O-trimethylsilylcyanohydrins (2) were prepared and converted to various compounds: α-hydroxyketones (3), dehydroxylated ketones (4), α,β-unsaturated ketones (9), tricyclic ketones (10), 1-ethoxycarbonyl-4- phenyl-1,2,4a,5,6,7,8,8a-octahydro-2-naphthalenone (13), 1- phenylperhydroisocoumarin (18) and 1,2,3,4,4a,10,11,11a-octahydro-5h- benzo[a,d]cyclohepten-10-one (20).

Disproportionation-Recombination Rate Ratios for Hydroaromatic Radicals

Relative rates for radical disproportionation (R. + R'. RH + R'd) and recombination (R. + R'. RR') have been determined in the liquid phase at 150 deg C for a series of reactions involving resonance-stabilized hydroaromatic radicals.Self-reactions were studied for the 1-tetralyl, 1-indanyl, 9,10-dihydro-9-phenanthryl, and 9,10-dihydro-9-anthryl radicals.Four cross-radical reactions involving benzyl, diphenylmethyl, and 1-tetralyl radical as H-atom acceptors were also examined.Rate constant ratios (kd/kr) span the range of 1.34 for the self-reaction of 9,10- dihydro-9-phenanthryl radicals to 0.05 for the self-reaction of 9,10-dihydro-9-anthryl radicals.When disproportionation reaction exothermicity is sufficiently small, -ΔHd -1 (210 kJ mol-1), disproportionation rate constants decrease with decreasing exothermicity.A fit of liquid-phase data yields ln (kd/kr) per H atom = -10.1 - 0.163 ΔHd (kcal mol-1).
