Stereoselective syntheses furnished geometrically pure cis- A nd trans-isomers from the same ynone under different conditions. The organic Michael acceptor backbone allowed β-oxovinylarsines to be easily applied to conjugate-addition reactions, and β-oxovinylarsines were reactive to nucleophiles, electrophiles, and transition metals. Unlike other arsenic precursors which are toxic or volatile or have low reactivity, β-oxovinylarsines bear a well-defined organic backbone that confers both stability and known reactivity. Remarkably, β-oxovinylarsines were also compatible with organometallic catalysts and did not decompose or deactivate the catalyst by chelation.||URI:||https://hdl.handle.net/10356/155189||ISSN:||0276-7333||DOI:||10.1021/acs.organomet.9b00587||Rights:||© 2020 American Chemical Society.
