I'm am planning to perform a MW synthesis using diethylene glycol monomethyl ether but was curious to know what other high boiling point solvents I could use that would act the same under MW conditions. Does anyone have experience using glycol ethers as solvents? The reaction would be run at 180 degrees for 10 mins.

Glycol ethers have been extensively used as reducing agents in the synthesis of various types of nanomaterials, such as metal oxides and silver.  These are a couple of references that might assist you, but basically they work well at high temperatures.  They are moderate microwave absorbers, so the reagents used will have to be microwave absorbing-meaning they will have to be polar or ionic if you want to get to high temperatures.  I've used DEG and PEG up to 300 C for synthesizing bimetallic iron species and EG at 180 C for synthesizing silver nanoparticles.  Glycol ethers are easy to work with, but do put off a small odor after being heated to high temperatures.

Thanks Keller my synthesis worked quite well and those references regarding glycol ethers will come in handy for my final report.

Did you performed the reaction at 180 degrees for 10 minutes.
