Recyclable copper(i)-catalyzed cascade C–S and C–N bond formation between 2-iodoanilines and 2-bromobenzenethiols towards functionalized phenothiazines

Abstract

A mesoporous SBA-15-immobilized L-proline-Cu(I) complex [L-proline-CuI-SBA-15] was prepared via immobilization of commercially readily available (4-(chloromethyl)phenyl)trimethoxysilane onto SBA-15, followed by reaction with N-Boc-trans-4-hydroxy-L-proline, and then the deprotection and coordination with CuI....
