Investigation of indium phosphide quantum dot nucleation and growth utilizing triarylsilylphosphine precursors

We have developed a two-phosphine strategy to independently tune nucleation and growth kinetics based on the relative reactivity of each precursor in the synthesis of indium phosphide (InP) quantum dots (QDs). This approach was allowed by the exploration

Linear free-energy relationship and rate study on a silylation-based kinetic resolution: Mechanistic insights

The substituent effect of different p-substituted triphenylsilyl chlorides on silylation-based kinetic resolutions was explored. Electron-donating groups slow down the reaction rate and improve the selectivity, while electron-withdrawing groups increase the reaction rate and decrease the selectivity. Linear free-energy relationships were found correlating both selectivity factors and initial rates to the σpara Hammett parameters. A weak correlation of selectivity factors to Charton values was also observed when just alkyl substituents were employed but was nonexistent when substituents with more electronic effects were incorporated. The rate data suggest that a significant redistribution of charge occurs in the transition state, with an overall decrease in positive charge. The linear free-energy relationship derived from selectivity factors is best understood by the Hammond postulate. Early and late transition states describe the amount of substrate participation in the transition state and therefore the difference in energy between the diastereomeric transition states of the two enantiomers. This work highlights our efforts toward understanding the mechanism and origin of selectivity in our silylation-based kinetic resolution.

The Role of Silicon-Oxygen Interactions in Determining the Stereochemical Outcome of the Peterson Reaction

The electronic effect of substituents on a benzene ring on the stereochemical outcome of the reaction of an α-triarylsilyl carbanion with an aldehyde is examined: the results can be interpreted in terms of the mode of approach of the carbanion towards the prochiral aldehyde, taking into account a variable oxygen-silicon interaction.

SELECTIVE REDISTRIBUTION REACTIONS OF ORGANOSILANES IN THE PRESENCE OF CHLOROPLATINIC ACID

Tetrasubstituted silanes of the general formula R2SiR'2 undergo redistribution reactions quite selectively in the presence of SiHCl3 and chloroplatinic acid.It is the smallest and seemingly the least hindered of the R groups on the tetrasubstituted silane which exchange most readily with a chloro group on trichlorosilane.
