Difluoroboryl complexes obtained from N-acyl hydrazones upon brief treatment with boron trifluoride and allylic silane serve as efficient acceptors of alkyl radicals. The reaction of the boryl chelates with carboxylic acids in the presence of an acridine-

The first radical ring-opening polymerization of 2-methylene-1,3-dioxepane in the presence of 2,2,6,6-tetramethyl-1-piperidinyloxy radical (TEMPO) has been achieved with di-tert-butyl peroxide as initiator to afford a chain polyester. The observations of

Radical and anionic polymerizations of methyl and tert-butyl α-(allyloxymethyl)acrylates (AMA and ABA, respectively) were undertaken to see whether five-membered ring formation through head-to-head and tail-to-tail additions can occur irrespective of the

On Radicals of Polynomial Rings
Acta Mathematica Hungarica, 2014We investigate connections in the behaviour of a ring and the polynomial rings over it with respect to a given radical.

ABSTRACT This paper is to investigate the class * of all prima rings without proper non-zero prima factors and to characterize the ‘minimal special radical’ containing the class * as well as the ‘maximal special radical’ the semisimple class of which contains the class *. This let us answer certain open questions put in [1] and [4].

The formation of cyclic ethers is a major product in the oxidation of hydrocarbons, and the oxidation of biomass derived alcohols. Cyclic ethers are formed in the initial reactions of alkyl radicals with dioxygen in combustion and precombustion processes

Radical Approach to Thioester-Containing Polymers.
Journal of the American Chemical Society, 2019A new approach to radical ring-opening polymerization is presented that employs a new thionolactone monomer to generate polymers with thioester-containing backbones.

AbstractIt is shown that the nth center of a radical ring coincides with that of its adjoint group, from which a result of Jennings is sharpened and a conjecture of his is confirmed.

(Opgedra aan Prof. Hennie Schutte by geleentheid van sy sestigste verjaarsdag.) Abstract In this note we introduce the concept of a special class of Γ-rings. The upper radical property determined by a special class is then called a special radical. We show that the prime radical, Levitzki nil radical and the nil radical are all special radicals.
