Abstract A mixture of potassium hydroxide and potassium phosphate was found to be an active reagent mixture for the cleavage of 2-hydroxypropyl-protected acetylenes. The reaction was performed in toluene at reflux temperature and gave terminal acetylenes in good to excellent yields within very short periods of time. Numerous other functional groups are tolerated. Supplementary materials are available

A modular synthetic approach paves the way to nanoscale platform molecules for supramolecular graphite surface patterns at the solid–liquid interface. While a perylenedye bound at the end of the pillar remains fixed above the molecule center and points into solution, a fullerene ester bound at the same position performs a tumbling motion that translates as a “haze” in the otherwise submolecularly
