Several approaches have been undertaken to realize the synthesis of a new tinorganyl compound with a 2,2Ј,6Ј,2ЈЈ-terpyridine moiety. A synthesis pathway consisting of five steps with an overall yield of 51 % was successful in producing Ph 3 Sn(CH 2 ) 3 OPhttpy [HOttpy = 2,6-bis(2Ј-pyridyl)-4Ј-(phydroxyphenyl)pyridine], and insight has been gained into (partial) halogenation reactions with this unprecedented tinorganyl compound. Halogenation with hydroiodic acid2406 produced a new dinuclear complex cation that resulted from head-to-tail coordination of two monocations. Furthermore, synthesis and yields of already known intermediates have been optimized. The products were analyzed and identified by 119 Sn NMR, 1 H NMR, and 13 C NMR spectroscopy and ESI mass spectrometry, as well as by means of single-crystal Xray diffraction.Supporting Information (see footnote on the first page of this article): Further details on single-crystal X-ray crystallography, electrospray ionization (ESI), mass spectrometry, nuclear magnetic reso-Eur.2410 nance (NMR) spectroscopy, energy dispersive X-ray (EDX) spectroscopy, and on the synthesis of 3.
