Living Anionic Addition Reaction of 1,1-Diphenylethylene Derivatives: One-Pot Synthesis of ABC-type Chain-End Sequence-Controlled Polymers

In this study, a 1:1 addition reaction using 1,1-diphenylethylene (DPE) derivatives, referred to as the "living anionic addition reaction", was established to regulate the sequence of vinyl compounds having negligible homopolymerizability. The stoichiomet

Composition containing diclofenapyr and pretilachlor

The invention discloses a composition containing diclofenapyr and pretilachlor, which is prepared by wrapping a core material with microencapsulated liquid. When the composition is used, the weed in the paddy field absorbs chitosan, and the chitosan can increase the absorption rate of the weed to the diclofenapyr and the pretilachlor, and the intermediate 9 on the chitosan surface is absorbed by the weed and the rice. , The damage to the rice caused by the diclofenapyr and the pretilachlor is greatly reduced, so that the composition does not affect the rice while killing weeds.

Combination of an anionic terminator multifunctional initiator and divergent carbanionic polymerization: Application to the synthesis of dendrimer-like polymers and of asymmetric and miktoarm stars

A new and versatile synthetic strategy that provides access to precisely defined and totally soluble multicarbanionic initiators has been implemented to obtain by divergent growth dendrimer-like samples of polystyrene (PS) (up to the seventh generation) o

Electron delocalization in cross-conjugated p-phenylenevinylidene oligomers

The synthesis, structure, and electronic properties of a series of cross-conjugated p-phenylenevinylidene oligomers with one to four double bonds are reported. The X-ray crystal structure of the compound with two double bonds reveals a nonplanar conformat

Non-linearity and non-additivity of substituent effects in solvolysis of 1,1-diphenylethyl p-nitrobenzoates

The solvolysis rates of 1,1-diarylethyl p-nitrobenzoates and chlorides Y-Ar(X-Ar)CMe-LG (LG = OPNB, Cl) have been determined conductimetrically at 25°C in 80% (v/v) aqueous acetone. A linear Yukawa-Tsuno (Y-T) correlation was found for the symmetrical subseries (X = Y), showing a precise additivity relationship for the whole substituent range with ρsym = -3.78 and rsym = 0.77. The unsymmetrical subsets (X ≠ Y) gave statistically less reliable Y-T correlations, the apparent p value decreasing significantly when the fixed substituent Y becomes more electron-donating, which is in line with expectations from the Reactivity-Selectivity Relationship. In the whole dispersion pattern, both strong p-π-donor and electron-withdrawing substituents in any fixed-Y subsets exhibit significant rate-enhancement deviations from the points of X = Y on the reference ρsym line, which suggests an anti-Hammond shift of the transition state. However, there was a precise Extended Bronsted Linear Relationship between the pKR+ values for the hydration of 1,1-diarylethylenes and the rates of solvolysis of the p-nitrobenzoates with a slope of unity (α = 1.03). This is direct, convincing evidence that there is no significant shift of the transition-state coordinate over the whole range of substituent change.

Intramolecular magnetic coupling between two nitrene or two nitroxide units through 1,1-diphenylethylene chromophores. Isomeric dinitrenes and dinitroxides related in connectivity to trimethylenemethane, tetramethyleneethane, and pentamethylenepropane

Isomeric vinylidenebis(phenylnitrenes) (N) and 1,1-bis[(N-oxy-tert-butylamino)phenyl]-2-methylpropenes (O) have been prepared, and their EPR fine structures and/or effective magnetic moments have been determined over a wide temperature range. The data wer

REGIOSPECIFIC SYNTHESIS OF AROMATIC COMPOUNDS VIA ORGANOMETALLIC INTERMEDIATES. I. para-SUBSTITUTED BENZENES

Para-substituted benzene compounds, p-XC6H4X' (X = CF3C(O) and X' = CH3, CO2H, C(O)CF3, C(O)CH3, C(O)H and SH) have been prepared via sequential metal-halogen exchange reactions between p-BrC6H4Br and n-C4H9Li and the appropriate electrophiles.Low reaction temperature is critical to stabilization of the various intermediates.The CF3 group has a pronounced effect on providing stability to the lithium hemiketal intermediates.
