2,2′ : 6′,2′‐Terpyridine

Abstract

2,2′ : 6′,2′‐Terpyridine intermediate: 22.5 g (0.1 mol) of 3,3‐bis(methylthio)‐1‐(2‐pyridinyl)‐2‐propen‐1‐one intermediate: 4′‐(methylthio)‐2,2′ : 6′,2″‐terpyridine product: 2,2′ : 6′,2″‐terpyridine

Red emitting [Ir(C^N)2(N^N)]+complexes employing bidentate 2,2′:6′,2′′-terpyridine ligands for light-emitting electrochemical cells

“…Literature procedures were followed for the preparation of tpy, 24 pytpy, 25 [Mepytpy][PF 6 ], 26 1, 25 2, 25 (15 mL) was heated in a microwave reactor for 30 min at 120 °C (P = 13 bar). The orange solution was then cooled to room temperature, and an excess of solid NH 4 PF 6 was added.…”

Strategies for Coupling Molecular Units if Subsequent Decoupling Is Required

“…In the 1970, there were practically only two methods of desulfurization available, and both were not applicable to many compounds: Raney nickel reduction and sodium amalgam reduction . Twenty years later, the number of available methods was substantially expanded to include those mediated by transition metals and sodium boride formed in situ . Since then, several new mild methods have been developed.…”

Synthesis of DNA Triangles with Vertexes of Bis(terpyridine)iron(II) Complexes

“…The terpyridine derivative 1 was synthesized as shown in Scheme . Oxidation of compound 2 4a-d with molecular oxygen in the presence of potassium tert -butoxide afforded 3 4e.…”

“…The terpyridine derivative 1 was synthesized as shown in Scheme . Oxidation of compound 2 4a-d with molecular oxygen in the presence of potassium tert -butoxide afforded 3 4e. Subsequent esterification of 3 with thionyl chloride in refluxing methanol followed by complete reduction using NaBH 4 provided 5 .…”
