Application

1-Iodo-2-(trimethylsilyl)acetylene may be used to investigate the reactivity of diamagnetic cobalt(I) complex, Tol-BDI((2-pp)2)Co [Tol-BDI((2-pp)2)H = 2-(4-tolyl)-1,3-bis(2-isopropylpyridyl)propenediimine]. It may be used for the synthesis of 1-(4-trimethylsilanylbuta-1,3-diynyl)pyrene, via Pd-coupling with 1-iodo-2-trimethylsilylacetylene.

A model for cobalamin was synthesized using a new monoanionic tetradentate nitrogen donor ligand; 2-(4-tolyl)-1,3-bis(2-isopropylpyridyl)propenediimine (Tol-BDI((2-pp)2)H) (1), which utilizes isopropylpyridines as pendant arms on a β-diketiminate (BDI) backbone. During the synthesis of 1, the rearrangement product, Tol-BDI((2-pp)(4-pp))H (2) was observed.
