  • METHODS FOR SYNTHESIZING COMPOUNDS AND RELATED COMPOSITIONS
    Publication number: 20260015330
    Abstract: Methods for synthesizing compounds are provided. A method of synthesizing a compound comprises obtaining a compound comprising an alpha halide group and a protecting group; and contacting the compound with at least one reagent sufficient to remove the protecting group (deprotect) and convert the alpha halide group to at least one of an alkenyl, an aldehyde, or any combination thereof, to obtain a reaction product at high purity. Related compositions are also provided, among other things.

  • MONOALKYL CYCLOPENTADIENE COMPOUNDS AND PROCESSES FOR PREPARING SAME
    Publication number: 20240116836
    Abstract: The disclosure provides methodology for the synthesis of mono-alkylated cyclopentadiene structures, which can be obtained via fulvene intermediates. In one embodiment, the cyclopentadiene ring is substituted with a trialkylsilyl moiety, which enables the further reaction with certain metal halides to form metal adducts. For example, the monoalkyl cyclopentadienes substituted with a trimethylsilyl group can be reacted with TiCl4 to provide R*CpTiCl3 complexes, wherein R* is a group of the formula wherein R1 and R2 are as defined herein.
