  • Methods of producing metal sulfides, metal selenides, and metal sulfides/selenides having controlled architectures using kinetic control
    Patent number: 10767112
    Abstract: The present invention is directed to methods of preparing metal sulfide, metal selenide, or metal sulfide/selenide nanoparticles and the products derived therefrom. In various embodiments, the nanoparticles are derived from the reaction between precursor metal salts and certain sulfur- and/or selenium-containing precursors each independently having a structure of Formula (I), (II), or (III), or an isomer, salt, or tautomer thereof, where Q1, Q2, Q3, R1, R2, R3, R5, and X are defined within the specification.

  • Synthesis of diazaphosphacycles
    Patent number: 7355073
    Abstract: A diazaphosphacycle may be synthesized by reacting a phosphine with a diimine and optionally one or more equivalents of an acid halide, a sulfonyl halide, a phosphoryl halide, or an acid anhydride in the substantial absence of O2 to form the diazaphosphacycle. The phosphine has the formula R1—PH2 where R1 is a substituted or unsubstituted aryl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted cycloalkyl group, or a substituted or unsubstituted ferrocenyl group.
