A general and efficient protocol has been developed to synthesise a series of novel porphyrin dimers with versatile aryl linkers via a simultaneous condensation-cyclisation-oxidation reaction of diverse bis(dipyrromethanes) with dipyrromethane-dicarbinol catalysed by indium(iii) chloride at room temperature in an efficient CH2Cl2 and CH3CN mixed-solvent. The reaction yields increased to 21–26 % based
