• PROCESS FOR THE PREPARATION OF SECONDARY AND TERTIARY AMINO-FUNCTIONAL SILANES, IMINOORGANOSILANES AND/OR IMIDOORGANOSILANES

  Iminoorganosilanes may be prepared by reacting aminoorganosilanes with organoimines by an amine exchange reaction. The resultant iminoorganosilanes can then be catalytically reduced to produce secondary and tertiary amino silanes. Imidoorganosilanes can be prepared by a similar amine reaction between aminoorganosilanes and organoimides. The imidoorganosilanes can also be reacted to produce tertiary amines. Water-sensitive silane reactants may be employed to yield water-sensitive imino, imido, or amino silane products.

  Iminoorganosilanes可以通过氨基有机硅烷与有机亚胺进行胺交换反应来制备。然后可以催化还原得到二级和三级氨基硅烷。通过类似的胺反应，可以制备Imidoorganosilanes。Imidoorganosilanes也可以被反应以产生三级胺。对水敏感的硅烷试剂可用于产生水敏感的imino、imido或氨基硅烷产品。

  The manufacture of polyetherquinoxalines may be accomplished by polymerization of quinoxaline and related monomers with a bisphenol under aromatic nucleophilic substitution reaction conditions. A method of manufacture includes contacting a substituted or unsubstituted quinoxaline having replaceable groups at the 2,3 positions with a bisphenol or a bisphenol derivative under aromatic nucleophilic substitution reaction conditions. The resulting polyetherquinoxalines contain quinoxaline groups joined by ether linkages at the 2 and 3 positions of the quinoxaline groups. In one example, the polyetherquinoxaline has a formula represented as wherein “n” is an integer from 1 to 10000, and R 1 , R 2 , R 3 , R 4 are independently hydrogen, methyl, CF 3 , tert-butyl, benzoyl, benzenesulfonyl, a sulfonic acid salt, an aliphatic group, an alicyclic group, or an aryl group, and Ar is an aromatic radical. These melt-processable polyetherquinoxalines can be prepared under relatively mild conditions, have excellent thermal and mechanical properties, and are organo-soluble, transparent and colorless thermoplastics.

  The invention provides a composition of matter of the formula (I): V—L—R where V is an organic group having binding affinity for an angiotensin II receptor site, L is a linker moiety or a bond, and R is a moiety detectable in in vivo imaging of a human or animal body, with the provisos that where V is angiotensin or a peptidic angiotensin derivative or analog then V—L—R is other than a non-metal radionuclide substituted peptide (e.g. 125 I substituted angiotensin II) and L—V is other than simply a peptide with a chelating agent amide bonded to a side chain thereof. This composition of matter may be used to image cardiovascular diseases and disorders.
