Relative Reactivities in Vinyl Copolymerization

Synopsis. From data in the literature on relatine rates of copolymerization it has been possible to evaluute two constants, Q and e , cheracteristic of a n individual monomer, which appear to account satisfactorily .for its behavior in copolymerization. The constant Q describes the “general monomer reactivity” and is apparently related to possibilities for stabilization in a radical adduct. The...

Nucleophilic reactivities of benzenesulfonyl-substituted carbanions.

Kinetics of the reactions of four benzenesulfonyl-stabilized carbanions (1a-d)- with reference electrophiles (quinone methides 2 and diarylcarbenium ions 3) have been determined in dimethyl sulfoxide solution at 20 degrees C in order to derive the reactivity parameters N and s according to the linear free-energy relationship logk(20 degrees C) = s(N + E) (eqn (1)). The additions of (1a-d)- to o...

Reactivities of Substituted α-Phenyl-N-tert-butyl Nitrones

In this work, a series of α-phenyl-N-tert-butyl nitrones bearing one, two, or three substituents on the tert-butyl group was synthesized. Cyclic voltammetry (CV) was used to investigate their electrochemical properties and showed a more pronounced substituent effect for oxidation than for reduction. Rate constants of superoxide radical (O2(•-)) reactions with nitrones were determined using a UV...

Difference in the Reactivities of H- and Me-Substituted Dinucleating Bis(iminopyridine) Ligands with Nickel(0)

The react iv i ty of dinucleating bis(iminopyridine) ligands bearing H (L, (N,N′)-1,1′-(1,4phenylene)bis(N-(pyridin-2-ylmethylene)methanamine)) or Me substituents (L, (N,N′)-1,1′-(1,4-phenylene)bis(N-(1(pyridin-2-yl)ethylidene)methanamine)) on the imine carbon atom with Ni(COD)2 (COD = 1,5-cyclooctadiene) has been investigated. Treatment of L with 2 equiv of Ni(COD)2 forms dinuclear Ni2(L )(COD...

PHOTOISOMERIZATION OF 1-VINYL-7,7- DIMETHYL BICYCLO [2.2.1] HEPTA-ZONE

The acetone sensitized photolysis of the title compound gave 2-(2- oxopropy1)-9,9- dimethyl bicyclo [3.3.l]nona-3-one. A bridgehead cyclopropane intermediate was then suggested for the formation of the photoproduct
