Abstract
AbstractThis review on homogeneous C-C bond-forming reactions to form alkenes focuses on hydrovinylation, hydroalkenylation, and cycloisomerization, and covers the literature published from ca. 1990 to early 2020. The account is arranged by reaction type, and then further categorized according to the alkene donors and alkene acceptors employed. This chapter highlights the potential of using well-controlled insertion catalysts in the green and catalytic synthesis of higher substituted alkenes. The methods described avoid the stoichiometric use of alkenyl halides and metallic reagents and serve as essential alternatives to those based on Heck reactions and related approaches.
