A wide selection of phosphine activators has been screened to improve the selection process in the asymmetric Appel reaction. Of the activators screened, hexachloroacetone (HCA) gave the highest selectivity with excellent yield, but at least one of i

Glycosyl chlorides, useful as glycosyl donors in glycoside synthesis and precursors in organic synthesis, can be easily prepared under solvent-free conditions by exposing a sugar hemiacetal to an equimolar mixture of PPh 3 and hexachloroacetone at 70

Chirally deuterated benzyl chlorides were prepared using novel, general hexachloroacetone/polymer-supported triphenylphosphine treatment of chirally deuterated benzyl alcohols. Doubly labeled protected tyrosine was obtained in 62% yield with 86% de a

An efficient one-pot synthesis has been developed of enantioenriched P-stereogenic phosphanes and phosphane boranes from the corresponding racemic phosphanes in excellent yield under asymmetric Appel conditions. The chiral auxiliary (menthol) can als

The insertion of aldehydes and ketones onto the germanium-nitrogen bond of trialkylgermylamines leads to α-aminoalkoxygermanes which are generally not very stable. Their decomposition leads to trialkylgermanium oxides and enamines or imines correspo

Thermal decarboxylation of sodium trichloroacetate in the presence of hexachloroacetone yields CO2, CO, CCl4, perchloroisopropenyl acetate and perchloroisopropenyl acrylate. A mechanism is suggested involving Cl+-abstraction by a CCl3− ion from the
