A stable four-membered N-heterocyclic carbene.
نویسندگان
چکیده
The synthesis of the first four-membered N-heterocyclic carbene is described. Depending on the substituents on the nitrogen atoms, it is possible to characterize at room temperature the carbene dimer or the free carbene. Crystallographic analyses are provided for these carbene species.

Stable four-pi-electron, four-membered heterocyclic cations and carbenes.
Replacement of halide from N-(haloboryl)formamidines for the weakly coordinating anion [B(C(6)F(5))(4)](-), using [Et(3)Si(toluene)](+)[B(C(6)F(5))(4)](-), induces a ring closure leading to the cationic four-pi-electron four-membered heterocycles [HC(N-2,6-diisopropylphenyl)(2)BR](+) [R = N(i-Pr)(2), Ph]. Subsequent deprotonation of the B-amino derivative affords the corresponding N-heterocycli...

متن کاملTheoretical investigations of the reactivities of saturated five-membered ring N-heterocyclic carbenes with heavier group 14 elements.
The potential energy surfaces for the chemical reactions of group 14 carbenes have been studied using density functional theory (B3LYP/LANL2DZ). Five saturated five-membered-ring N-heterocyclic carbene Dipp[upper bond 1 start]N(CH(2))(2)N(Dipp)E[upper bond 1 end]: (five-ring-E:) species, where E = C, Si, Ge, Sn and Pb, have been chosen as model reactants in this work. Also, four kinds of chemic...
متن کاملSpiro-fused six-membered N-heterocyclic carbene: a new scaffold toward unique properties and activities.
A six-membered N-heterocyclic carbene fused with a spiro-scaffold is designed. The new NHC shows stronger σ-donation ability than typical 5-membered NHCs. This property leads to interesting reactivities of this spiro-fused six-membered NHC. For example, the NHC-BF3 Lewis pair complex can be readily prepared by using LiBF4 as the BF3 source, or through a direct bond-reconstruction of the tetrafl...
متن کاملDihaloborenium cations stabilized by a four-membered N-heterocyclic carbene: electron deficiency compensation by asymmetric structural changes.
The synthesis, characterization and X-ray analysis of dichloro- and dibromo-borenium cations stabilized by a 4-membered carbene are reported. The ligand's structural changes, atypical for similar systems, were caused by coordination to electron deficient fragments and its CN2P ring strain.
