The triphenylphosphine-benzoyl peroxide (TPP-BPO) reagent initiates stereospecific benzoylation of secondary carbinol stereocenters with essentially complete inversion of stereochemistry.Monobenzoylations of 1,2-propanediol and styrene glycol with TPP-BPO and triphenylphosphine-diethyl azodicarboxylate-benzoic acid reagents afford a predominance of the more sterically encumbered C-2 benzoate with complete inversion of stereochemistry.Formation of a quintessential 1,3,2lambda5-dioxaphospholane intermediate, followed by proton-assisted and highly stereoselective ring opening of the phospholanes to isomeric oxyphosphonium ions, allows for Arbusov displacement of triphenylphosphine oxide by benzoate anion.This rationale adequately accounts for both the high chemoselectivity and the stereochemistry of the reactions.
Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 4254-15-3Reference of 4254-15-3
