Bis(η5-cyclopentadienyl)diphenyltitanium-catalyzed hydrosilylation of ketones

Abstract: Bis(η5-cyclopentadienyl)diphenyltitanium activated a Si–H bond of diphenylsilane, methylphenylsilane, and phenylsilane effectively to bring about the reaction with ketones giving hydrosilylation products, alkoxysilanes, in good yields with good selectivity.

Conversion of Disilanes to Functional Monosilanes. XIII. The Palladium Catalyzed Reductive Coupling of Benzylidene Dichlorides and Benzylidyne Trichlorides Using Disilanes as Reducing Agents

Abstract: The reaction of benzylidene dichlorides or benzylidyne trichlorides with 1,2-dichloro-1,1,2,2-tetramethyldisilane or hexamethyldisilane proceeded smoothly in the presence of acatalytic amount of Pd(PPh3)4 to give (E)-stilbenes or (E)- and (Z)-α,β-dichlorostilbenes in high yields, respectively. Also, in the presence of the palladium(0) catalyst, α,α-dichlorobenzyltrimethylsilanes reacted with hexamethyldisilane yielding (E)-α,β-bis(trimethylsilyl)stilbenes in quantitative yield.

Polar Substituent Constants for Substituted Phenyl Groups. The Extended Taft Equation.

Abstract: Values of the σ* constants have been defined for some m- and p-substituted phenyl groups from the 29Si–H coupling constants for a series of m- and p-substituted phenylsilanes, phenylmethylsilanes, and phenyldimethylsilanes. The σ* constants for the groups, XC6H4, were found to be directly related to the Hammett σ constants for the ring substituents, X. From this correlation the σ* constants for a number of other substituted phenyl groups have also been calculated. Examples have been presented in which a simple relationship holds between the Taft polar substituent constants including the newly derived σ* constants and molecular properties for a series of compounds covering both aliphatic and aromatic substances. Correlations of reactivities with the extended σ* values have been illustrated and the implications of the results are discussed.

Single-Electron Transfer and Single-Electron Transfer Degenerative Chain Transfer Living Radical Polymerization

Abstract: The special of Chemical Review informs about studies conducted on single-electron transfer and single-electron transfer degenerative chain transfer living radical polymerization. Researchers have demonstrated that living radical polymerization (LRP) can be significantly effective for the synthesis of tailored polymers. The special issue aims at covering the latest progress in two related polymerization methodologies that rely on single-electron transfer (SET), single-electron transfer degenerative chain transfer living radical polymerization (SET-DTLRP), and single-electron transfer living radical polymerization (SET-LRP). It is demonstrated that SET-DTLRP proceeds through SET initiation and competition of SET activation, deactivation, and degenerative transfer (DT). SET-LRP proceeds exclusively through a SET initiation, activation, and deactivation. It is also revealed that the two techniques have arose from investigations into Cu-catalyzed LRP initiated with sulfonyl halides.
