Microwave heating considerable im- proves the yields and reaction times achieved with conventional heating and is even effective in cases where conventional heating fails. It is demonstrated that the choice of the solvent dramatically affects the outcome of the reaction. — (GARCIA, L.; PLA-QUINTANA*, A.; ROGLANS, A.; PARELLA, T.; Eur. J. Org.
