The synthesis of spirobifluorenyl-substituted PPV  by the dehydrohalogenation of 1,4-bis(bromomethyl)-2-(2'-ethylhexyloxy)-5-(2"-((2"',7"'-di-tert-butyl)-9",9"'-spirobifluorenyl)) benzene using large excess of potassium tert-butoxide
is one example of the Gilch procedure.
Key products covered by the agreement include Sodium Potassium alloy (NAK), Potassium tert-Butoxide
(KTB), and other Potassium Metal alkoxides.
Poly(2,5-di-n-butoxy-p-phenylene vinylene) (DBPPV) was synthesized in a mixed solvent of xylene and tertbutyl alcohol via a dehydrochlorination route, using potassium tert-butoxide
as the initiator.
