Metathesis between [Li{([Me3Si]2C)P(C6 H4-2-CH2NMe2)2}] (1) and either RbOR or CsOR (R = 2-ethylhexyl) gives the heavier alkali metal phosphinomethanide complexes [Rb{([Me3Si]2C)P(C6H4-2- CH2-NMe2)2}]n (4) and [Cs{([Me3Si]2C)P(C6H4-2- CH2NMe2)2}-(toluene)]n (5), respectively, after recrystallization. Compounds 4 and 5 represent the first examples of complexes containing a Rb-PR3 or Cs-PR3 bond.
