Abstract
A hexacoordinate phosphoranate bearing two Martin ligands and two methyl groups was synthesized by the reaction of the monocyclic phosphorane bearing a hydroxy group with KH, and was crystallized in the presence of 18-crown-6 ether. The crystal structure of the phosphoranate could be regarded as an intermediate model in the reaction of the O-equatorial methylphosphorane with a methyl anion.
Dedicated to Professor Marian Mikołajczyk from the CBMiM PAN in Łódź, Poland, on the occasion of his 70th birthday.
