ALLYLCHLOROTINS AS ALLYLATING AGENTS OF ACYL CHLORIDES

Allylchlorotins of the type R(3-n)AllSnCln (R = alkyl or All; All = CH2=CHCH2 or cis/trans-CH3CH=CHCH2, n = 1-3) undergo uncatalyzed coupling with acyl chlorides under mild conditions.This reaction as well as the corresponding addition reaction to ketones are much faster when Cl is replaced by NCS group in the organotin derivative.

Photochemical Deconjugation of α,β-Unsaturated Ketones

It is shown that 'photochemically inert' α,β-unsaturated ketones can undergo synthetically useful u.v.light induced deconjugation via photoenolization in the presence of a mild base, and the mechanism of this reaction has been examined by measurement of the relative quantum yield of deconjugation as a function of base and solvent; the results indicate two competing mechanisms for the reketonization of the intermediate dienols, one involving a thermal 1,5-sigmatropic hydrogen shift, and the other base-catalysed proton transfer.

Titanium-promoted Allyl Transfer to Carbon Monoxide and Other Unsaturated Molecules

Carbonylation of Cp2Ti-(?-allyl) yields Cp2Ti(CO)2 and triallylmethanol; reactions of Cp2Ti-(?-allyl) and Cp2Ti-(?-1-methylallyl) with other ligands proceed via insertion or allyl-elimination pathways.
