    Triphenyl[(5,10,15,20-tetraphenylporphyrin-2-yl)methyl]phosphonium chloride, bromide, and trifluoroacetate were obtained by reacting 2-hydroxymethyl-5,10,15,20-tetraphenylporphyrin with, respectively, hydrogen chloride and triphenylphosphine, triphenylphosphonium hydrobromide, or a mixture of triphenylphosphine, trifluoroacetic acid and trifluoroacetic anhydride. All the salts afforded high yields in a model Wittig reaction with terephthalic aldehyde.
