Nj. Hardman et al., Synthesis and characterization of the monomer Ga{(NDippCMe)(2)CH} (Dipp = C6H3Pr2i-2,6): a low valent gallium(I) carbene analogue, CHEM COMMUN, (20), 2000, pp. 1991-1992
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 featu
res a V-shaped, two-coordinate, six-electron gallium(I) center electronical
ly analogous to a singlet carbene carbon.
