TL;DR: In this paper, it was shown that the presence of a tertiary amine, apart from assisting the metallation reaction, is essential for the occurrence of the addition of α-pinene, whereas up to four molecules of ethylene added to hex-1-ene, only one or two, depending on the reactant ratios, added to metallated αpinene.

TL;DR: In this paper, a set of alkyl group parameters that are transferable and additive has been derived from the ionization potentials of the corresponding radicals, which are related to spectroscopic electronegativities.
Abstract: A set of alkyl group parameters that are transferable and additive has been derived from the ionization potentials of the corresponding radicals. These parameters, which are related to spectroscopic electronegativities, have been correlated with 13 C NMR data of (a) alkyl halides, (b) aliphatic hydrocarbons, (c) aromatic hydrocarbons, (d) p-alkyl-substituted acetophenones, (e) olefinic compounds, (f) secondary alcohols, (g) aldehydes and ketones, and (h) 2,6-alkyl-substituted p-benzoquinones

TL;DR: The molar volumes at 20 o C of the sequences n-RH, cycloallanes, n-RF and n-RCl have been correlated with the corresponding carbon numbers in the n-allyl group or in X(CH) n X.
Abstract: The molar volumes at 20 o C of the sequences n-RH, cycloallanes, n-RF, n-RCl, n-RBr, n-RI, n-RCN, n-ROH, n-RSH, n-RNH 2 , n-RCOOH, n-RCOOMe, n-RCOOEt, n-ROAc, n-R 1 SR 2 -n, n-RCOMe, Cl(CH 2 ) n Cl, Br(CH 2 ) n Br, and n-RCH=CH 2 have been correlated with the corresponding carbon numbers in the n-allyl group or in X(CH) n X
