Superbase-catalysed addition of methanol to propyne and allene: an expedient synthesis of 2-methoxypropene

Superbase-catalysed addition of methanol to propyne and allene: an expedient synthesis of 2-methoxypropene

In the superbase catalytic systems Bu tOK/NMP, Am tOCs/NMP and KOH/DMSO, methanol readily adds to propyne and allene at 100–120 °C and atmospheric pressure to afford 2-methoxypropene in 80–97% yield with 75–94% methanol conversion.
