Reactions of titanium alcoholates Ti(OR)4 (R = n-Bu, t-Bu) with tertiary organic and organometallic hydroperoxides

tert-Butyl and cumyl hydroperoxides in the reactions with Ti(OR) 4 are reduced to alcohols with the evolution of oxygen via formation of titanium-containing peroxides and trioxides. The pathways of the reactions of Ti(OR)4 with triphenylelement hydroperoxides R3EOOH (E = C, Si, Ge) depend on element E and on the structure of R; the reactions involve the rearrangement of the peroxides, and with (n-BuO)4Ti the alkoxy group is oxidized either with preservation or with breakdown of the hydrocarbon skeleton.

Reaction of organoelement hydrides R3EH (E = Si, Ge) with metal tert-butylate (M = Al, Ti)-tert-butyl hydroperoxide oxidative systems

Trialkyl(aryl)silanes and -germanes effectively react with metal (Al, Ti) tert-butylate-tert-butyl-hydroperoxide under mild conditions (room temperature, benzene or tetrachloromethane) mainly by the element-hydrogen bond. The character of the products depends on the nature of the element, the structure of the radical bound to it, and the solvent. The process is radical in nature. It includes the stages of formation of element-centered radicals and their reaction with the oxygen generated by the system. The intermediate organometallic peroxides can also acts as oxidants for the element (Si, Ge)-hydrogen bonds. 2005 Pleiades Publishing, Inc.

Reactivity of 2,6-diethyl-4,8-dimethyl-1,5-dioxo-s-hydrindacene towards radical, anionic and cationic germylation

The synthesis and diastereoisomeric resolution of 2,6-diethyl-4,8-dimethyl- 1,5-dioxo-s-hydrindacene allowed the determination of the structure of the meso compound by X-ray diffractometry. The diastereoisomers were inactive towards radical germylation but reacted with acidic hydrogermanes or germylithium yielding α-germylated alcohols. By contrast, they were poorly reactive towards germylamines or SET reactions. This diketone acts as an efficient spin trap in radical hydrogermylation of alkenes.

Syntheses and Structural Characterizations of a Novel Bowl-Type Germanol and Its Derivatives

A novel bowl-type triarylgermyl group, tris(2,2″,6,6″ -tetramethyl[1,1′:3′,1″-terphenyl]-5′-yl)germyl (denoted as TRMG), was designed, and a germanol and its derivatives bearing this framework were synthesized. X-ray crystallographic analysis of TRMG-OH (5) revealed that there is no OH...O hydrogen bonding between adjacent molecules, although the possible presence of a weak intermolecular OHmellip;π interaction was suggested. In sharp contrast to organogermanols known so far, 5 is extremely resistant to self-condensation; no digermoxane was obtained when 5 was subjected to the conditions under which Ph3GeOH (8) affords the corresponding digermoxane. On the other hand, germanol 5 was readily converted to various derivatives. The crystal structure of TRMG-SH (12) was also determined.

Reaction de derives a liaison germanium-azote (germylamines, cyclogermazanes et germa-imines transitoires) avec la di-t-butyl-3,5-orthoquinone

Several germanium-nitrogen compounds were treated with 3,5-di-t-butylorthoquinone (1).In the case of germylamines R3GeNMe2 (R = Et, Ph), 1,2 and 1,4 adducts were formed, as shown by 1H NMR spectroscopy.The thermally unstable 1,4 adduct, decomposes with nitrene elimination to give 2,2-dialkyl or 2,2-diaryl (6,8-di-t-butyl)-4,5-benzo-2-germa-1,3-dioxolane.The 1,2 adduct, through intermolecular redistribution, leads to digermyloxide (R3Ge)2O and a gem-diamine with partial regeneration of the starting quinone 1.These addition reactions proceed through a monoelectric transfer mechanism, with formation of a transient o-semiquinonic radical identified by ESR spectroscopy.This transient radical leads to O-germyl 3,5-di-t-butylcatechol by hydrogen abstraction from the solvent.The proposed mechanism explains the formation of the germylated compounds as well as the organic by-products.Similar reactions were observed between cyclodigermazanes and 1.The 1,4 cycloaddition generates germadioxolanes with nitrene expulsion, whereas the 1,2-cycloaddition leads to the germoxane and conjugated ketoimine, or diimine.The latter is a good trapping agent for the nitrene formed in the decomposition of the 1,4 adduct.Both the 1,4 and 1,2 cycloadduct decompositions imply transient germaimine formation.The same germaimine, formed at room temperature from intramolecular dehydrogenation of the hindered R2ClGeNHR' by 1,8-diazabicyclo-7-undecene) gives the same reaction products.
