Lithium Diisopropylamide (lda) as an Efficient Reducing Agent for Thioketones - Mechanistic Consideration
Treatment of thiocarbonyl compounds with excess LDA leads to the corresponding thiols or sulfides depending on the work-up procedure. The mechanistic scenario for this unusual reduction pathway is discussed.

متن کاملLithium diisopropylamide-mediated ortholithiations: lithium chloride catalysis.
Ortholithiations of a range of arenes mediated by lithium diisopropylamide (LDA) in THF at -78 degrees C reveal substantial accelerations by as little as 0.5 mol % of LiCl (relative to LDA). Substrate dependencies suggest a specific range of reactivity within which the LiCl catalysis is optimal. Standard protocols with unpurified commercial samples of n-butyllithium to prepare LDA or commercial...

An Efficient LDA Algorithm for Face Recognition
It has been demonstrated that the Linear Discriminant Analysis (LDA) approach outperforms the Principal Component Analysis (PCA) approach in face recognition tasks. Due to the high dimensionality of a image space, many LDA based approaches, however, first use the PCA to project an image into a lower dimensional space or so-called face space, and then perform the LDA to maximize the discriminato...
متن کاملLithium diisopropylamide: solution kinetics and implications for organic synthesis.
Lithium diisopropylamide (LDA) is a prominent reagent used in organic synthesis. In this Review, rate studies of LDA-mediated reactions are placed in the broader context of organic synthesis in three distinct segments. The first section provides a tutorial on solution kinetics, emphasizing the characteristic rate behavior caused by dominant solvation and aggregation effects. The second section ...
