  • Catalytic method for obtaining substituted (triorganosilyl)alkynes and their derivatives
    Patent number: 9518069
    Abstract: New (triorganosilyl)alkynes and their derivatives having general formula R1—C?C—Z are provided along with methods for the preparation of (triorganosilyl)alkynes and their derivatives having the general formula R1—C?C—Z. The methods may include silylative coupling of terminal alkynes with halogenotriorganosilanes in the presence of an iridium catalyst and a tertiary amine.
    Type: Grant
    Filed: July 10, 2015
    Date of Patent: December 13, 2016
    Assignee: ADAM MICKIEWICZ UNIVERSITY

  • (Triorganosilyl)alkynes and their derivatives and a new catalytic method for obtaining new and conventional substituted (triorganosilyl)alkynes and their derivatives
    Patent number: 9108994
    Abstract: The present invention relates to new (triorganosilyl)alkynes and their derivatives having general formula 1 R1—C?C—Z (I) In its second aspect, this invention relates to a new selective method for the preparation of new and conventional (triorganosilyl)alkynes and their derivatives having the general formula 1, by the silylative coupling of terminal alkynes with halogenotriorganosilanes in the presence of an iridium catalyst and a tertiary amine.

  • Functionalized polyhedral octavinylsilsesquioxanes and a method to obtain the functionalized polyhedral octavinylsilsesquioxanes
    Patent number: 9018400
    Abstract: A new functionalized polyhedral octavinylsilsesquioxanes having the general formula 1, in which R1 denotes: (1) any aryl group other than a non-substituted phenyl or a phenyl substituted in position four with a halogen or the groups-trimethylsilylethynyl, 4,4,5,5-tetramethyl-1,3-dioxaborolane-2-yl, 3,4-dimethoxyphenyl, 3?,5?-bis(methoxycarbonyl)phenyl or benzo[d][1,3]-dioxol-5-yl; (2) any heteroaryl group; or (3) groups including coupled aromatic rings. Additionally, a method to obtain new and known functionalized polyhedral octavinylsilsesquioxanes having the general formula 1, by the silylating coupling of octavinylsilsesquioxane with olefins in the presence of a ruthenium complex catalyst.
