title: Electrophilic activation of aldehydes "on water": a facile route to dipyrromethanes.
abstract: Shaken .. and stirred: Dipyrromethane, an important building block in porphyrin chemistry, can be easily accessed by a reaction performed on water in the absence of Lewis acids. Thus, a variety of substituted dipyrromethanes were prepared in moderate to good yields using a range of aldehydes.
