Sterically Hindered Phosphonium Salts: Structure, Properties and Palladium Nanoparticle Stabilization

Sterically Hindered Phosphonium Salts: Structure, Properties and Palladium Nanoparticle Stabilization

A new family of sterically hindered alkyl(tri-<i>tert</i>-butyl) phosphonium salts (<i>n</i>-C<sub>n</sub>H<sub>2n+1</sub> with <i>n</i> = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20) was synthesized and evaluated as stabilizers for the formation of...
