Poly(ethylene glycol) Dimethyl Ethers (PEGDME): Efficient and Recyclable Solvents for Aryne involved Reactions

A variety of aryne reactions were demonstrated in poly(ethylene glycol) dimethylether (PEGDME) as solvent without the need of additives. The reactions proceeded well, and good yields of products were observed with PEGDME. Further, the advantage of PEG solvents for recycling and reusable nature was demonstrated.
