Transition‐Metal‐Free Alkylation of N‐Heterocycles with Nitriles via Heteroarylphosphonium Intermediates [PDF]

open access: yes
Heteroarylphosphonium salts are easily accessible, versatile intermediates in functionalization of N‐heterocycles. Direct C−C bond formation by net substitution of the phosphine has so far required transition metal catalysts, the use of strongly basic ...

A Stibonium-Modified Clay and its Polystyrene Nanocomposite [PDF]

open access: yes, 2003
Triphenylhexadecylstibonium trifluoromethylsulfonate has been prepared and ion-exchanged with sodium montmorillonite to obtain a new organically-modified clay. The clay has higher thermal stability than an ammonium clay; only a portion of the alkyl chain
