One-Pot Dual C?C Coupling Reaction via Site Selective Cascade Formation by PdII-Cryptate of an Amino-Ether Heteroditopic Macrobicycle

Selectivity of aryl iodo over ethynyl iodo toward the Suzuki cross coupling reaction is explored by utilizing a palladium complex of amino-ether heteroditopic macrobicycle. Subsequently, unreacted ethynyl iodide undergoes homocoupling reaction in the same catalytic atmosphere, thereby representing a cascade dual C?C coupling reaction. Furthermore, this approach is extended for novel one-pot synthesis of unsymmetrical 1,3-diynes.

Copper(I) iodide catalyzed cross-coupling reaction of terminal alkynes with 1-bromoalkynes: A simple synthesis of unsymmetrical buta-1,3-diynes

A simple synthesis of unsymmetrical buta-1,3-diynes by cross-coupling of terminal alkynes with 1-bromoalkynes in the presence of copper(I) iodide and tris(o-tolyl)phosphine was developed that gives good yields under simple and mild reaction conditions. The scope and limitations of the cross-coupling reaction were investigated. Georg Thieme Verlag Stuttgart · New York.
