Four different porphyrin–imidedyads bearing different central metals (zinc or rhodium) and different substituents on the porphyrin macrocycles (tert‐butyl or methoxy) were synthesized for singlemoleculardiode measurements. The molecules were designed to separate the donor component (porphyrin) from the acceptor component (imide) by bonding in a perpendicular arrangement, thus enhancing the rectification

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
