A Polymer-Supported Rhodium Catalyst that Functions in Polar Protic Solvents [PDF]
, 2016 Highly cross-linked macroporous polymers are excellent supports for heterogenizing rhodium alkene hydrogenation and hydroboration catalysts. The permanent pore structure of the support enables high conversions and excellent yields with minimal workup ...

Silver-Mediated Allylic Disulfide Rearrangement for Conjugation of Thiols in Protic Media [PDF]
, 2009 International audienceAlkyl and aryl allyl disulfides are induced to undergo the desulfurative allylic rearrangement by silver nitrate in protic solvents at room temperature, thereby removing the necessity for the use of phosphines as thiophilic reagents.
