Metallic amidoborates, their anions and processing for making them are described which comprise at least one metallic cation or cationic complex and an anion comprising the moiety (R1)2N -B(R2)3, wherein each R1 independently represents Z1(Z1A)p-, wherein each Z1 and Z1A independently represents a carbon atom or a silicon atom and each p independently represents the integer 2 or 3 and each R2 independently represents a fluorine atom or Z2(Z2A)k -, wherein each Z2 independently represents a carbon atom, nitrogen atom or a silicon atom, each Z2A independently represents a hydrogen atom, a carbon atom or a silicon atom, and k represents a positive integer equal to the valence of Z2, wherein at least one of the R2 substituents is Z2(Z2A)k -. The metallic amidoborate compounds may be used to make metalated organic compounds, which in turn may be reacted with an electrophile to make organic compounds functionalized by the electrophile residue. The metallic amidoborate bases described herein are exceptionally stable, so that functionalization of the organic compound may be carried out rapidly and with high yield at room temperature.
