Abstract

Homoleptic LiNacNac forms simple donor-acceptor complexes with N,N′-dicyclohexylcarbodiimide (CyN= C= NCy), triphenylphosphine oxide (Ph3P= O), and benzophenone (Ph2CO). These crystallographically characterized compounds could be regarded as model intermediates en route to reducing the N= C, P= O, and C= O bonds of unsaturated substrates. Heteroleptic NacNacMg(TMP) intriguingly functions as a TMP nucleophile both with t-BuNCO and t-BuNCS, producing a urea or thiourea derivative respectively attached to Mg, though the NacNac ligand in the former reaction also engages noninnocently with a second t-BuNCO molecule via insertion at the reactive NacNac backbone γ-carbon site.
