  • Process for the preparation of manganese complexes of salen compounds
    Patent number: 6794526
    Abstract: A process for the preparation of manganese complexes of salen compounds which comprises carrying out the reaction of a salen compound with a manganese compound in DMF is described. In a preferred embodiment, the salen compound itself is synthesised likewise in DMF and reacted without intermediate isolation to form the manganese complex.

  • Process for the preparation of N,N- dialkylaminophenyl alkanols
    Patent number: 5962739
    Abstract: The present invention provides a process for the production of an N,N-dialkylaminophenyl alkanol having the formula: ##STR1## in which R.sub.1 and R.sub.2, independently, are C.sub.1 -C.sub.4 alkyl, R.sub.3 is hydrogen, halogen, cyano, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy and n is an integer from 1 to 4, comprising reacting an aminophenyl alkanol having the formula: ##STR2## in which R.sub.3 and n have their previous significance, with at least two moles of a dialkylsulfate having the formula: ##STR3## in which R.sub.1 and R.sub.2 have their previous significance. N,N-dialkylaminophenyl alkanols so obtained are valuable as intermediates for a wide range of end-products and are also useful, e.g., as accelerators for the peroxide-catalyzed polymerization of vinyl monomers, especially in polymerizable or curable formulations employed in dental applications.
