Abstract
The present disclosure provides compositions and methods for metathesizing a first alkenyl or alkynyl group with a second alkenyl or alkynyl group, the composition comprising a ruthenium metathesis catalyst and a photoredox catalyst that is activated by visible light.
Claims21
A composition for metathesizing a first alkenyl or alkynyl group with a second alkenyl or alkynyl group, the composition comprising:
- a ruthenium metathesis catalyst and a photoredox catalyst that is activated by visible light.
A method for chemical metathesis, comprising applying visible light to (i) one compound comprising a first alkenyl or alkynyl group and a second alkenyl or alkynyl group or (ii) a first compound comprising a first alkenyl or alkynyl group and a second compound comprising a second alkenyl or alkynyl group, in the presence of a ruthenium metathesis catalyst and a photoredox catalyst that is activated by visible light.
A method of spatially controlling a metathesis, comprising:
- forming a mixture of a ruthenium metathesis catalyst, a photoredox catalyst, and one or more compounds susceptible to metathesis;
- and
- applying visible light to one or more regions of the mixture so as to give rise to one or more metathesized regions and one or more unmetathesized regions.
A method of spatially controlling a metathesis, comprising:
- applying visible light to a ruthenium metathesis catalyst, a photoredox catalyst, and one or more compounds susceptible to metathesis, the applying being performed so as to give rise to one or more metathesized regions,
- at least one of the ruthenium metathesis catalyst and the photoredox catalyst being linked to a substrate, the substrate optionally being stationary.
