A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 51805-45-9, Name is 3,3′,3”-Phosphinetriyltripropanoic acid hydrochloride, molecular formula is C9H16ClO6P. In an article, author is Cheng, Kunpeng,once mentioned of 51805-45-9, Formula: C9H16ClO6P.
Hydroxy-assisted regio- and stereoselective synthesis of functionalized alkenes via phosphine-catalyzed beta ‘-umpolung addition of o-hydroxy aromatic aldimines to allenoates
An unprecedented -umpolung addition of o-hydroxy aromatic aldimines with allenoates has been developed under the catalysis of phosphine. The reaction provides an efficient approach to the synthesis of functionalized alkenes in moderate to good yields with high stereoselectivities under mild conditions. The asymmetric version of this beta’-umpolung addition has also been studied using chiral phosphines.
