  • Method for the preparation of compounds with cyclic monothiocarbonate groups
    Patent number: 11897861
    Abstract: A process prepares a compound containing at least one cyclic monothiocarbonate group, wherein a salt of an acidic compound with at least one acidic hydrogen atom is reacted with a compound of formula (I), wherein one of the groups R1 to R4 is a group of formula (II), -A-X, with A representing an organic group with at least one carbon atom and X representing a halide, and the remaining groups R1 to R4 independently from each other represent hydrogen or an organic group with 1 to 50 carbon atoms.
    Type: Grant
    Filed: January 17, 2020
    Date of Patent: February 13, 2024
    Assignee: BASF SE

  • Process for the preparation of compounds with at least one alkylene group and at least one thiol or thiolate group
    Patent number: 11814344
    Abstract: A process synthesizes a compound with at least one alkylene group and at least one thiol or thiolate group. The process involves reacting a compound with at least one five-membered cyclic monothiocarbonate group with a starter selected from a compound with at least one thiol group, from a compound with at least one hydroxy group, or from a basic inorganic composed; to obtain a compound with at least one alkylene group and at least one thiol or thiolate group and carbon dioxide.

  • PROCESS FOR PREPARING A HYDROXY GROUP FUNCTIONALIZED THIOETHER
    Publication number: 20230340205
    Abstract: A process can be used for preparing a compound A having n groups of formula (I). In Formula (I), X is C2-C12-alkylene or C2-C12-alkylene substituted with C1-C4-alkoxy, C1-C4-alkylthio, and/or interrupted with O or S; R1, R2, and R3 are independently of one another hydrogen or C1-C4-alkyl: and n is an integer of 1, 2, 3, 4, 5, or 6. The process involves reacting a compound B having n —SH groups with a compound C of formula (II), in the presence of a free radical generator.
