yields of the title compounds are improved by protection of the precursor propynal ethynyl groups with dicobalt octacarbonyl: Lindsey porphyrin synthesis results in brown cobalt-carbonylprotected compounds which are oxidatively deprotected to yield green ethynyl-substituted porphyrins.
The enthalpies of sublimation of 5,10,15,20-tetraphenylporphine (CA registry number 917-23-7, TPP) and 5,10,15,20-tetrakis(4-methoxyphenyl)porphine (CA registry number 22112-78-3, TMPP), were determined by the Knudsen effusion method using a quartzcrystal microbalance in a system designed specially
