Relay cross metathesis reactions of vinylphosphonates
Beilstein 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.

Capture cross sections from (p,d) reactions [PDF]
EPJ Web of Conferences, 2017 Cross sections for compound-nuclear reactions involving unstable targets are important for many applications, but can often not be measured directly. Several indirect methods have been proposed to determine neutron capture cross sections for unstable ...
