A series of monoalkylated organosilicon compounds of the form RSi(OPO)2Cl (OPO = 1-oxo-2-pyridinone; R = Me, tBu, Ph, CH2Ph, p-tolyl) was synthesized and characterized by 1H , 13C, and 29Si NMR spectroscopy, and elemental analysis. X-ray crystallographic analyses revealed two different coordination environments in the series, with 5-coordinate complexes formed with R = Me, tBu, and 6-coordinate complexes formed with R = Ph, CH2Ph, p-tolyl. Dynamic behavior was observed in each of the five complexes using variable-temperature NMR spectroscopy.
