Process for producing amidine sulfonic acid intermediates for guanidines |
| abstract |
An efficient synthesis of quanidines, e.g. of the formula (III), by oxidizing a thiourea, e.g. of the following formula (II): <IMAGE> (III) <IMAGE> (II) with H2O2 and a molybdenum catalyst to yield an aminoiminomethane sulfonic acid which can then be reacted with an amine followed by optional transamination steps. |
