Porphyrin compounds having a surface attachment group coupled thereto at the 5 position are described. The surface attachment group has the formula:
wherein R is —CHCH
2
or —CCH and Ar is an aromatic group. Methods and intermediates useful for making such compounds are also described.

using 5-((difluoromethyl)sulfonyl)-1-phenyl-1H-tetrazole as a CF2Hradical difluoromethyl precursor was developed to afford nitriles including a CF2H group. A low-cost, stable, easily handled 5-((difluoromethyl)sulfonyl)-1-methyl-1H-tetrazole (DFSMT) was synthesized and applied as the radicalCF2H reagent. Using DFSMT as the radicalCF2H precursor, the oxyl-difluoromethylation of alkenes was developed
