✦ Synopsis

On page 3860 of the original article [1] we reported:

"The preparation of the phosphonium salt 16 was carried out, starting from the aldehyde 13, according to the synthetic scheme reported in a preliminary communication by Bonfantini and Officer in 1993. [24] However the detailed experimental procedure was never published, hence a careful description of the synthesis and characterisation of intermediate porphyrins 14, 15 and 16 is given in the Experimental Section."

Recently, Prof. D. L. Officer informed us that the detailed experimental procedure for the synthesis of compound 16 was published in his article "Efficient synthesis of free-base 2-formyl-5,10,15,20tetraarylporphyrins, their reduction and conversion to [(porphyrin-2yl)methyl]phosphonium salts". [2] We apologize for any inconvenience this omission might have caused.
