  • [Bis(trihydrocarbylsilyl)aminosilyl]-functionalized styrene and a method for its preparation
    Patent number: 10723822
    Abstract: The invention relates to [bis(trihydrocarbylsilyl)aminosilyl]-functionalized styrene and a method for its preparation. The invention further relates to the use of the styrene derivative in the preparation of a copolymer thereof. The styrene derivative is preferably used as comonomer in the production of elastomeric copolymers. Alternatively, or additionally, it is used in the preparation of a polymerization initiator.

  • Method for protecting hydroxyl or amine or thiol functions, novel compounds with protected hydroxyl or amine or thiol groups, as well novel compounds for the implementation of this method
    Patent number: 9290521
    Abstract: A novel method of simultaneously protecting two functions which are same or different, namely hydroxyl, amine, or thiol ones, particularly in sugars, polyalcohols, nucleosides, nucleotides, peptides, and nucleic acids during an organic synthesis, and to novel compounds for implementing this method, as well as to the method of obtaining these compounds. Method of simultaneously protecting two hydroxyl, amine, or thiol functions according to the invention by carrying out a protecting reaction between a compound having at least two free hydroxyl, amine, or thiol groups, and the disilane of formula 1, where R stands for Cl or Br, or I, or a substituent of formula 2, where X1, X2, X3, X4 are the same or different.
