Three very bulky β-diketimine protio-ligands (ArNacnacH, (Ar) N=C (But) 2CH2, Ar = 2, 4, 6-tricyclohexylphenyl TCHP; 2, 6-dicyclohexylphenyl DCHP; TCHP/Dip, Dip = 2, 6-diisopropylphenyl) have been synthesised. These have been used to prepare monomeric, three-coordinate β-diketiminato magnesium. . .
Jiang et al. (Thu,) studied this question.
