Patent number: 5858905Abstract: Catalyst systems which comprise a transition metal and a pyrophosphite ligand are particularly effective as catalysts for hydrosilation reactions. The transition metal is from groups 7-11 of the Periodic Table, and the pyrophosphite has the following formula: ##STR1## wherein E and E' are independently a direct bond, --S--, --Se--, or --CR.sub.9 R.sub.10 -- where R.sub.9 and R.sub.10 are independently hydrogen or alkyl of 1-18 carbon atoms, and R.sub.10 can also be phenyl. R is H or methyl, R.sub.1-8 are independently H, C.sub.1-18 alkyl, C.sub.5-12 cycloalkyl, or C.sub.7-15 phenylalkyl.Type: GrantFiled: July 23, 1997Date of Patent: January 12, 1999Assignee: Ciba Specialty Chemicals CorporationInventors: Andrea R. Smith, Stephen D. Pastor

Patent number: 5324848Abstract: A new class of vanadium phosphate materials has been created using hydrothermanl self-assembly techniques. Of particular interest is that these materials comprise a vanadium phosphate framework structure about an organic template that after removal leave a microporous structure. These materials typically are produced by a reaction in an aqueous solution that includes one or more phosphate sources, one or more vanadium or vanadium oxide sources, an alkali metal or alkali-earth metal sources, and an organic amine or diamine templating agent.Type: GrantFiled: March 11, 1993Date of Patent: June 28, 1994Assignee: NEC Research Institute, Inc.Inventors: Robert C. Haushalter, Victoria G. Soghomonian, Jon A. Zubieta
