摘要:
Coordination complexes can have a metal center with at least one unsubstituted catecholate ligand and at least one monosulfonated catecholate ligand or a salt thereof bound thereto. Some coordination complexes can have a formula of D g Ti(L 1 ) x (L 2 ) y , in which D is a counterion selected from NH 4 + , Li + , Na + , K + , or any combination thereof; g ranges between 2 and 6; L 1 is an unsubstituted catecholate ligand; L 2 is a monosulfonated catecholate ligand; and x and y are non-zero numbers such that x+y = 3. Methods for synthesizing such coordination complexes can include providing a neat mixture of catechol and a sub-stoichiometric amount of sulfuric acid, heating the neat mixture to form a reaction product containing catechol and a monosulfonated catechol or a salt thereof, and forming a coordination complex from the reaction product without separating the catechol and the monosulfonated catechol or the salt thereof from one another.

摘要:
The invention relates to a process for the preparation of acyloxybenzenesulfonates starting from carbonyl halides and salts of phenolsulfonic acid which have a low water content. Surprisingly, it was discovered that acyloxybenzenesulfonates can be prepared in high yields and good grades, irrespective of the grade or reactivity of the phenolsulfonic acid derivative, if the reaction of the phenolsulfonic acid with an alkanecarboxylic acid derivative is carried out in an aliphatic or aromatic solvent in the presence of 0.5 to 25% by weight of a polyglycol ether.
