TL;DR: In this article, the relative Arrhenius parameters have been determined for the addition of trifluoromethyl radicals to vinyl chloride (XCl), vinyl bromide (XBr), acrylonitrile (XCN), methyl vinyl ketone (XCOCH3), 2-methylbut-2-ene, and to iso-butene, taking the rate of addition to ethylene as standard.
Abstract: Relative Arrhenius parameters have been determined for the addition of trifluoromethyl radicals to vinyl chloride (XCl), vinyl bromide (XBr), acrylonitrile (XCN), methyl vinyl ketone (XCOCH3), 2-methylbut-2-ene, and to iso-butene, taking the rate of addition to ethylene as standard. Addition occurred virtually exclusively at the unsubstituted end of all the olefins. The relative rates of addition at 164°C show very little variation. The preexponential terms for addition to the CH2 ends are constant within experimental error, and the small variations in rate are due principally to the activation energy term. The present results are put on an absolute scale using the previously determined Arrhenius parameters for addition to ethylene and are compared with data for other similar monomers determined previously.

TL;DR: In this paper, reactions of carbon nucleophiles with tricarbonyl(cyclohexadienyl)iron tetrafluoroborate are described, and the anion of nitromethane reacts with the tricaronyl-5-exo-(nitromethyl)cyclohexa-1,3-dieneiron(0), which was reduced with zinc in acetic acid/hydrochloric acid.

TL;DR: The tri-isopropylphenylsulphonylhydrazone of methyl vinyl ketone undergoes the Shapiro reaction to give 2-lithiobuta-1,3-diene which reacts with aldehydes to give two-substituted dienes with high regioselectivity as mentioned in this paper.

TL;DR: In this paper, the selective formation of either regioisomer of both β-oxo (5a−c) and δ-oxon (4a −c) lactones from 3α−c was achieved by varying the reaction conditions.
