Abstract

DC60 (09/02/41) This invention relates to the synthesis of a highly reactive, high-yield ruternium-osmium carbine metathesis catalyst from readily available substrates. The catalyst may be in a general form (chemical formula) where: M is ruternium or osmium; X and X1 independently are any anionic ligands; L and L1 are electron-neutralizing ligands; Each R and R to the power of 1 represents a hydrogen or one substituent from the following substituents: C2-C20 alkynyl, C2-C20 alkynyl, C1-C20 alkyl, aryl, C1-C20 carboxylate, C1-C20 alkoxy, C2-C20 alkynyloxy, C2-C20 alkynyloxy, aryloxy, C2-C20 alkoxycarbonyl, C1-C20 alkylthio, C1-C20 alkonsulfonyl, and C1-C20 alkonsulfinyl. In addition, the substituent may be replaced by one or two selected substituents from C1-C5 alkyl, halogen, C1-C5 alkoxy, and aryl. When the aryl substituent is phenyl, it may be replaced by another substituent. One or more selected from groups containing halogens, C1-C5 alkyls, or C1-C5 alkoxys, are prototypes. Specific synthesis for vinyl alkylidenes is performed where R is hydrogen and R⁻¹ is -CH₂CR⁻¹² R⁻¹³, and vinyl alkylidenes are also revealed. In addition to simple synthesis (typically one-step synthesis), the reaction can generally be carried out at room temperature or higher, and the resulting products are often used without further post-synthesis purification. This invention relates to the synthesis of a highly reactive, high-yield rusternium and osmium carbine metathesis catalyst from readily available precursors. The catalyst may be in a generic form (chemical formula) where: M is rusternium or osmium; X and X1, independently, are any anionic ligands; L and L1 are electron-neutralizing ligands; Each R and R1 represents a hydrogen or one substituent from the following substituents: C2-C20 alkynyl, C2-C20 alkynyl, C1-C20 alkyl, aryl, C1-C20 carboxylate, C1-C20 alkoxy, C2-C20 alkynyloxy, C2-C20 alkynyloxy, aryloxy, C2-C20 alkoxycarbonyl, C1-C20 alkylthio, C1-C20 alkonsulfonyl, and C1-C20 alkonsulfinyl. Additionally, the substituent may be replaced by one or two selected substituents from C1-C5 alkyl, halogen, C1-C5 alkoxy, and aryl. When the aryl substituent is phenyl, it may be replaced by another substituent. One or more selectable groups containing halogens, C1-C5 alkyls, or C1-C5 alkoxys are used as prototypes. Specific synthesis for vinylalkylidenes where R is hydrogen and R1 is -CH₂CR12R13, and vinylalkylidene catalysts are also revealed. In addition to simple synthesis (typically a one-step synthesis), the reaction can generally be carried out at room temperature or higher, and the resulting products are often used without further purification after synthesis.
