Electric Literature of 499-40-1. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal

A new di-2-pyridylamine ligand with an appended azobenzene group (2-C5H4N)2N-4-C6H4-NN-Ph, dpaa, is reported. This ligand readily forms the platinum(ii) complexes [PtMe2(dpaa)], 1, and [PtCl2(dpaa)], 2. Complex 1 is electron-rich and it undergoes oxidative addition with I2, MeI or PhCH2Br to give the corresponding organoplatinum(iv) complexes [PtI2Me2(dpaa)], [PtIMe3(dpaa)] or [PtBrMe2(CH2Ph)(dpaa)]. Both the ligand dpaa and its platinum complexes undergo photoswitching by trans-cis isomerization about the NN linkage.
