The preparation of 2-iminoimidazolines 3a-3f has been accomplished by the Staudinger reaction of the carbenes 1,3-di-tert-butylimidazolin-2-ylidene (1a), 1,3-diisopropyl-4,5-dimethylimidazolin-2-ylidene (1b), 1,3- diisopropylimidazolin-2-ylidene (1c), 1,3

We report the synthesis of an acyclic two-coordinate germylene supported by two bulky and electron donating N-heterocyclic guanidine [IPr=N]- ligands (IPr = [(HCNDipp)2C:]; Dipp = [2,6-iPr2C6H3/

The phosphinoimino-2-imidazoline 4 was synthesized by a salt elimination reaction between LiNIPr [NIPr = 1,3-bis(2,6-(diisopropylphenyl)imidazolin-2-ylidenamino)] and 2-chloro-1,3,2-diazaphospholene. DFT study revealed that the HOMO of 4 involves the lone pair orbitals on the P atom and the N atom at the exocyclic P–N bond. Compound 4 displays selectivity in coordinating to acids. Thus, the N atom at the exocyclic P–N bond coordinates to a hard acid (HCl) which eventually led to the cleavage of the P–N bond, while the central P atom forms a dative bond with a soft Lewis acid, BH3.
