Organomercury( II) and organotin( IV) compounds with nitrogen-containing substituents

Article abstract of DOI:10.1016/0022-328X(95)06081-7

New compounds of the type ArHgCl, ArCH₂HgCl, Ar₂Hg, (ArCH₂)₂Hg, ArSnPh₃ and ArCH₂SnPh₃ are described. The aryl groups carry various substituents, but all have a group in the 2-position which involves a nitrogen atom which could in principle coordinate to the metal atom, e.g. -NMe₂, -CH₂NMe₂, -CONH₂, -NHCO^tBu, -SO₂NMe₂, -oxaz (oxaz = 4,4-dimethyl-2-oxazoline). Full ¹H and ¹³C NMR assignments are made for all the compounds; the data provide no evidence for N → Hg coordination in solution. IR data suggest that such interaction is, at most, very weak in the solids.
