20080269501 | Synthesis of Phosphono-Substituted Porphyrin Compounds for Attachment to Metal Oxide Surfaces - A method of making a phosphono-substituted dipyrromethane comprises reacting an aldehyde or acetal having at least one phosphono group substituted thereon with pyrrole to produce a phosphono-substituted dipyrromethane; and wherein the phosphono is selected from the group consisting of dialkyl phosphono, diaryl phosphono, and dialkylaryl phosphono. Additional methods, intermediates and products are also described. | 10-30-2008 |
20090137795 | NEW ROUTE TO FORMYL-PORPHYRINS - A method of making a 5-formylporphyrin, comprises the steps of: condensing a 5-acetaldipyrromethane with a dipyrromethane-1,9-dicarbinol to produce a porphyrin having an acetal group substituted thereon at the 5 position; and then hydrolyzing said porphyrin to produce said 5-formylporphyrin. Products and intermediates useful in such methods, along with methods of making such intermediates, are also described. | 05-28-2009 |
