We report a catalytic strategy that generates rhodium-carbynoids by selective diazo activation of designed carbyne sources. We found that rhodium-carbynoid species provoke C(sp2)-C(sp2) bond scission in alkenes by inserting a monovalent carbon unit between both sp2-hybridized carbons. This skeletal remodeling process accesses synthetically useful allyl cation intermediates that conduct to valuable allylic building blocks upon nucleophile attack. Our results rely on the formation of cyclopropyl-I(III) intermediates able to undergo electrocyclic ring-opening, following the Woodward-Hoffmann-DePuy rules.

In the presence of titanium tetrachloride, 1-ethoxy-3-trimethylsilyl-1-propyne easily reacts with many α-haloketones to lead to dienic conjugated esters; an α-ethylenic lactone may be obtained when the halogen is on a tertiary carbon atom.

Principal Component Analysis (PCA) was carried out on the basis of property descriptions for a set of α-halogenated ketones and aldehydes. The obtained PCA model showed that the chemical behaviour of the compounds with 1-ethoxy-3-trimethylsilylprop-1-yne
