Synthesis and characterization of the monomer Ga{(NDippCMe)(2)CH} (Dipp = C6H3Pr2i-2,6): a low valent gallium(I) carbene analogue

The reaction between solvent free Li{(NDippCMe)(2)CH} (Dipp = C6H3Pr2i-2,6), 'GaI' and potassium in toluene afforded Ga{(NDippCMe)(2)CH} 1 which features a V-shaped, two-coordinate, six-electron gallium(I) center electronically analogous to a singlet carbene carbon.
