Relay cross metathesis reactions of vinylphosphonates [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2014
Dimethyl (β-substituted) vinylphosphonates do not readily undergo cross metathesis reactions with Grubbs catalyst and terminal alkenes. However, the corresponding mono- or diallyl vinylphosphonate esters undergo facile cross metathesis reactions.

Cross-coupling Reactions of Monosubstituted Tetrazines [PDF]

open access: yesOrganic Letters, 2021
A fast and mild method for the Pd-catalyzed cross-coupling reaction of monosubstituted 3-bromo-1,2,4,5-tetrazine is presented. Investigation of silver-based additives revealed that Ag2CO3 is the optimal mediator, enabling the process without the need for strong bases or high temperatures.
