Article abstract of DOI:10.1007/BF01150751

2-(Triphenylstannyloxy)-3,6-di-tert-butyl-1,4-benzoquinone (1) was obtained from the potassium salt of 3,6-di-tert-butyl-2-hydroxy-1,4-benzoquinone and triphenyltin bromide in methanol and characterized by x-ray diffraction analysis, electronic, IR, and NMR spectroscopy.According to x-ray diffraction data, the single crystal of 1 has the structure of a chain metal polymer with bridging hydroxy-para-quinone ligands; the coordination number of tin is six.Complex 1 is reduced by cobaltocene to the corresponding radical anion.In solutions, 1 reacts with metal-centered radicals SnPh3, PbPh3, and Mn(CO)5 with formation of paramagnetic binuclear ortho-semiquinone complexes. Keywords: 2-triphenylstannyloxy-3,6-di-tert-butyl-1,4-benzoquinone, synthesis, x-ray diffraction analysis, electronic absorption spectra, IR spectroscopy, NMR spectroscopy, reaction with radicals.
