KLc2a–c by reaction with potassium hydride in tetrahydrofuran (THF). An improved synthesis of HLc1c is also reported. Reaction of KLa–c with Group 13 metal salts MCl3 (M = Al, Ga or In) gives monomeric derivatives [M(κ4-La–c)Cl2] 3–5 in good yields. The crystal structure of [In(κ4-Lb)Cl2] 5b has been determined and confirms the six-coordinate, cis-dichloride structures proposed for these complexes. Reaction
