Customized Buchwald-type phosphines bearing an "inverted" pyrimidinium betaine as an aryl group surrogate - Synthesis and coordination chemistry with gold(I)

Résumé

A new ligand scaffold inspired by Buchwald-type phosphines is disclosed. Its design consists of the formal replacement of the distal aryl group of the original archetype by a pyrimidinium betaine connected to the o-phosphinophenyl moiety through the C-5 position of its malonate subunit. A productive synthetic pathway towards this phosphine is described along with its ability to coordinate to a gold(I) center. A weak bonding interaction between the metal center and the malonate group is observed in the solid state.
