Investigating the effects of steric hindrance on the coordination of 2-aminothiazoyl based ligands

Varying the bulk of the substituent in 2-(diphenylphosphino)aminothiazole (dppat) 2-(diphenylphosphino)amino-4-methylthiazole (Medppat)and 2-(diphenylphosphino)amino-4-tert-butylthiazole (Budppat) changes the hemilabile behaviour of the ligand.
