A heterogeneous Chan-Lam coupling reaction between sulfonyl azides and arylboronic acids was achieved in MeOH at room temperature in the presence of 10 mol% of an l-proline-functionalized MCM-41-immobilized copper(i) complex [MCM-41-l-proline-CuCl] under air, yielding a variety of N-arylsulfonamides in excellent yields. The new heterogeneous copper complex can be prepared from commercially readily available and inexpensive reagents, and recovered by simple filtration of the reaction solution and recycled at least 8 times without any decreases in activity.

The title compound afforded four different types of crystals as pseudopolymorphs upon crystallization from a variety of different solvents. Single-crystal X-ray analysis revealed that the nonsolvated crystals exclusively formed a zigzag chain motif throug

A highly chemo- and regioselective approach for the construction of ortho-amino triarylphosphine oxides has been achieved through a C-P cross-coupling reaction involving quinone imine ketals (QIKs) with Ar2P(O)H and catalyzed via a Lewis base. This alternative protocol provided a wide substrate scope with excellent yields (82-95%), and a variety of ortho-amino triarylphosphines were obtained with high yields (87-95%) via further reductive reaction. Furthermore, this reaction could be scaled-up and several synthetic transformations were accomplished for the construction of functionalized organophosphorus.
Preparation of acid-labile resins with halide linkers and their utility in solid phase organic synthesis

Mild and efficient preparation of acid-labile resins with displaceable halide linkers (3 and 4, X = Br and I) is described. These resins can be used in combinatorial organic synthesis of numerous drug-scaffold libraries. Their synthetic utility is exemplified by high yielding N-alkylations with structurally and electronically diverse sets of aliphatic and aromatic amines. Amongst the various resins modified and evaluated in this study, Wang resin derived bromo resin (3, X = Br) offers the best practical choice with respect to loading, stability, and chemical reactivity.
