TL;DR: In this paper, a new method was developed for the synthesis of 5 and 6-keto carboxylic acids by the addition of cyclopentanone and of cyclohexanone in presence of t-butyl peroxide to α-olefins with subsequent oxidation of the 2-alkylcyclopentanones and 2 -alkylcyclohexenones with chromium trioxide.

TL;DR: In this article, free-radical addition of dicarboxylic acid esters to α-olefins leads to the formation, In high yields, of α-alkyldicaroxyl acid ester.
Abstract: 1.
Free-radical addition of dicarboxylic acid esters to α-olefins leads to the formation, In high yields, of α-alkyldicarboxylic acid esters. The reaction may be employed for the preparative synthesis of α-alkyidicarboxylic acids.
2.
Carboxylic acids (or their esters) add on to esters of unsaturated acids with the formation of dicarboxylic acid esters.

TL;DR: The synthesis of a series of secondary alcohols has been carried out by the addition of C5-C10 primary alcohols to C6-C13 α-olefins as mentioned in this paper.
Abstract: 1.
The synthesis of a series of secondary alcohols has been carried out by the addition of C5–C10 primary alcohols to C6 – C13 α-olefins. The reaction initiator was t-butyl peroxide.
