It comprises treating a derivative of desferrioxamine B, in which the amino nitrogen and the hydroxy oxygen of at least one of the hydroxamic acid groupings carries an organic silyl group, with an organic acylating agent and then removing the silyl groups present. The novel N- and O-silylated starting materials can be manufactured, preferably in situ, by reacting an appropriate derivative of desferrioxamine B that has at least one hydroxy group and the amino group in free form, with an organic silicon halide.Type: GrantFiled: January 23, 1990Date of Patent: September 17, 1991Assignee: Ciba-Geigy CorporationInventors: Heinrich Peter, Theophile Moerker

Patent number: 5017717Abstract: Difunctional halo silicon amide compounds are prepared by cleaving the nitrogen-silicon bond in a nitrogen-silicon heterocycle with a reactive halide. The reaction is straight forward with no intermediates or byproducts. The halo functionality is capable of capping any SiOH group. When the other functionality is an acrylamide, the capped entity may be polymerized or crosslinked by free radical initiators of the acrylamide functionality thereby producing useful products such as paper release coatings and photoresists.Type: GrantFiled: October 30, 1990Date of Patent: May 21, 1991Assignee: Dow Corning CorporationInventors: Antony P.
