Reactivity studies of N-heterocyclic carbene complexes of germanium(II)

The chemistry of three N-heterocyclic carbene (NHC) complexes of GeR 2, where R = Cl (1), OtBu (2), Mes (3) (Mes = 2,4,6-trimethylphenyl), toward 2,3-dimethylbutadiene (DMB), 3,5-di-tert- butylorthoquinone, methyl iodide, pivalic acid, and benzophenone is reported. Upon heating, 2 and 3 cyclize with DMB to yield a germacyclopentene and free NHC. In contrast, 1 does not react with DMB. PB1PBE/6-311+G(d,p) model chemistry shows that the cycloaddition reactions of NHC-GeX2 (X = F, Cl) with butadiene are not thermodynamically favorable. 3,5-Di-tert-butylorthoquinone reacts rapidly with 1-3 to form cyclic products; in the case of 1 and 2, the NHC remains coordinated to the germanium, resulting in a hypervalent species. Compounds 1-3 react with methyl iodide by displacement of I-; in each case [NHC-GeR2Me]+ is produced. Only compound 3 reacts in a controlled fashion with pivalic acid; both 1:1 and 1:2 adducts were characterized. Benzophenone failed to react with 1 or 2 but did undergo cycloaddition with 3. In comparison with uncomplexed GeR2 species, the NHC-GeR2 complexes are less reactive. The prospect of using NHC-GeR2 as a synthon for GeR2 appears to be reaction specific.

Dimesitylgermylidene p-toluene sulfonamide: A new stable germanium-nitrogen doubly bonded species

A new stable germanium doubly bonded species is obtained by dehydrohalogenation of the corresponding N-halogenogermyl p-toluene sulfonamide. The dimesitylgermylidene p-toluene sulfonamide is a stable and very reactive reagent leading to addition reactions

Stable germa-imines: synthesis and reactivity of orthosubstituted anilinodimesitylgerma-imines

The orthosubstituted anilinodimesitylgerma-imines Mes2Ge=NAA (1) and Mes2Ge=NAE (2) where NAA is N-(dimethylanthranilamide) and NAE is N-(methylanthranilate) have been prepared by dehydrohalogenation of the corresponding halogenogermylamines.They are rare

Sur la stabilisation d'une germa-imine par effet sterique et mesomerie

Delithiochloration of N-lithio-N-dimesitylchlorogermyl-3-amino-2-methyl-thiophoate at low temperature leads to the corresponding germa-imine, stabilized by the steric effects of mesityl substituents linked to germanium and possibly by mesometric effects w

N-Mesityl dimesitylgerma-imine

N-Mesityldimesitylgermaimine (1) which is obtained by photolysis of trimesitylgermylazide has also been detected in the reaction of dimesitylgermylene with mesitylazide. 1 was characterized at room temperature by its pseudo-Wittig reaction with benzaldehy

Addition 1,4 de divers organo- et organohalogeno-hydrogermanes sur la di-t-butyl-3,5 orthoquinone

The thermal 1,4-addition of triorganohydrogermanes R3GeH(R=Et, Ph) with 3,5-di-t-butylorthoquinone leads to their corresponding mono-O-germylated catechols in good yields.Similarly, the organohalohydrogermanes give the 2,2-di-organo- (or 2,2-organohalo)(6,8-di-t-butyl)-4,5-benzo-2-germa-1,3-dioxolanes after dehydrochlorination of transient mono-O-chlorogermylated catechols.Since these reactions are only slightly dependent on solvent and radical initiators, the mechanism probably involves monoelectronic transfer with the formation of a radical anion pair in the first step.The ESR measurements show the transient formation of a paramagnetico-semiquinonic species which supports the proposed mechanism.

Cycloaddition of Germylenes to 3,5-Di-t-butylorthoquinone

The germylenes X2Ge, RGeX and R2Ge (X= halogen, OR; R= alkyl or aryl) react at room temperature with 3,5-di-t-butyl orthoquinone by regioselective cycloaddition.The corresponding substituted 2-germa-1,3-dioxolans are formed similarly in good yields, but t
