  • Patent number: 9505714
    Abstract: The invention provides processes and materials for the efficient and costeffective functionalization of alkanes and heteroalkanes, comprising contacting the alkane or heteroalkane and a soft oxidizing electrophile comprising Se(VI) or Te(VI), in an acidic medium, optionally further comprising an aprotic medium, which can be carried out at a temperature of less than 300 C. Isolation of the alkylselenium or alkyltellurium intermediate allows the subsequent conversion to products not necessarily compatible with the initial reaction conditions, such as amines, stannanes, organosulfur compounds, acyls, halocarbons, and olefins.

  • Patent number: 9096623
    Abstract: A method for preparing a radiotracer precursor SnADAM is revealed. The method overcomes shortcomings of conventional synthesis methods including lower yield rate and time-consuming. Moreover, Pd/C catalyst and hydrogen gas are used to catalyze reduction reaction for avoiding the generation of a large amount of intermediate products with similar structures. Thus there is no need to perform isolation and purification processes. The yield rate of the intermediate products is also increased so that its impact on the low yield rate of the final product SnADAM is minimized. A part of the reaction is significantly accelerated by using tris(dibenzylideneacetone)-dipalladium(0) (Pd2(dba)3) as a catalyst. Thus the production time of SnADAM is shortened.

  • Publication number: 20090297423
    Abstract: The reaction of halo-boron compounds (B—X compounds, compounds having one or more boron-halogen bonds) with silanes provides boranes (B—H compounds, compounds having one or more B—H bonds) and halosilanes. Inorganic hydrides, such as surface-bound silane hydrides (Si—H) react with B—X compounds to form B—H compounds and surface-bound halosilanes. The surface bound halosilanes are converted back to surface-bound silanes electrochemically. Halo-boron compounds react with stannanes (tin compounds having a Sn—H bond) to form boranes and halostannanes (tin compounds having a Sn—X bond). The halostannanes are converted back to stannanes electrochemically or by the thermolysis of Sn-formate compounds. When the halo-boron compound is BCl3, the B—H compound is B2H6, and where the reducing potential is provided electrochemically or by the thermolysis of formate.
