Influence of phase transfer catalyst structure on selectivity
Dehmlow, E. V.
, p. 1998 - 2005 (2007/10/03)
A concise review is given of systematic studies concerned with the tuning of regio-, "frequentio-", chemo-, and diastereoselectivity by the structure or type of phase transfer catalyst. - Keywords: phase transfer catalysis; regioselectivity; selectivity control; stereoselectivity; C/O-alkylation; C/N-alkylation.

Regioselectivity of the Alkylation of Ambident Anionic Species on Alumina or in the Presence of 'Solid Hexamethylphosphoric Triamide'
Bram, Georges,Geraghty, Niall,Nee, Gerard,Seyden-Penne, Jacqueline
, p. 325 - 326 (2007/10/02)
C-Alkylation of the acetoacetate anions and of sodium naphthoxide is highly favoured on alumina, while O-alkylation of the acetoacetate anion predominates in tetrahydrofuran in the presence of solid hexamethylphosphoric triamide.
