Gold Sulfonium Benzylide Complexes Undergo Efficient Benzylidene Transfer to Alkenes

The gold sulfonium benzylide complexes [(P1)AuCHPh(SR1R2)]+ {B[3,5-CF3C6H3]4}? [P1=P(tBu)2o-biphenyl; R1, R2=-(CH2)4- (1 a); R1=Et, R2=Ph (1 b); R1=R2=Ph (1 c)] were synthesized by reaction of the gold α-chloro benzyl complex (P1)AuCHClPh with sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate and excess sulfide. Complexes 1 undergo efficient benzylidene transfer to alkenes and DMSO under mild conditions without external activation. Kinetic analysis of the reaction of 1 c with styrene was consistent with the intermediacy of the cationic gold benzylidene complex [(P1)AuCHPh]+ (I).

Formation and reactivity of gold carbene complexes in the gas phase

A series of ligated gold(I) carbenes (where the ligand is Ph3P, Me2S, or an N-heterocyclic carbene, NHC) were formed in the gas phase by a variety of methods. Gold(I) benzylidenes could be formed using Chens method of dissociating an appropriate phosphorus ylide precursor. The resulting carbene undergoes an addition reaction with olefins to give an adduct. The adduct undergoes a second gas-phase reaction with an olefin, where presumably a cyclopropanation product is displaced by the second olefin molecule. Both steps in the process were analyzed with linear free energy relationships (i.e., Hammett plots). Under collision-induced dissociation conditions, the adduct undergoes competing processes: (1) dissociation of the cyclopropanation product to give ligated gold(I) species and (2) metathesis to give a more stable gold(I) carbene. Attempts to form less stable gold(I) carbenes in the gas phase by Chens approach or by reactions of diazo species with the ligated gold(I) cations were not successful-processes other than carbene formation are preferred or the desired carbene, after formation, rearranges rapidly to a more stable species. In accord with other recent work, the data suggest that coordination to a ligated gold(I) cation in the gas phase may not offer sufficient stabilization to carbenes to prevent competition from rearrangement processes.

Synthesis and reactivity of a new pyranoquinoxaline

3-Methyl-3,4-dihydro-1H-pyrano[3,4-b]quinoxalin-1-one (2) was prepared from a series of 3-methyl-4,5,10,11-tetrahydropyrano[4,3-b][1,5]benzodiazepin-1(3H)-one derivatives (1) bearing various substituents at position 11. The formation of this quinoxaline i

Ruthenium(I)-catalyzed cyclopropanation reactions with (trimethylsilyl)diazomethane and aryldiazomethanes

The polymeric ruthenium(I) complex [Ru2(CO)4(μ-OAc)2]n is a suitable catalyst for the cyclopropanation of mono-, 1,1- as well as 1,2-disubstituted, and trisubstituted alkenes with (trimethylsilyl)diazomethane, phenyl-diazomethane, and (4-cyanophenyl)diazomethane. Trisubstituted alkenes are cyclopropanated with a remarkable degree of syn-selectivity.

Conversion of non-activated alkenes into cyclopropanes with lithiated sulfones under nickel catalysis

Summary -Lithiated alkyl ierf-butyl sulfones convert alkenes into cyclopropane derivatives under nickel catalysis. The new reaction appears to differ from the known cyclopropanation reactions from both the stereochemical and the electronic points of view. Elsevier.

Formation of symmetrical alkenes by homocoupling of metallated sulfones under nickel catalysis

Summary -Allylic sulfones undergo a coupling reaction with organometallic compounds (Mg or Li) not only with copper catalysts but also with iron or nickel salts. With 7,7-disubstituted allylic sulfones and also saturated aliphatic sulfones, however, another reaction was observed whereby two molecules of the starting sulfone are coupled to give symmetrical alkenes. The scope of this reaction was investigated. Elsevier.

Unusual Temperature-Dependent Isotope Effects in the Reactions of Phenylcarbene with Cyclohexene and Cyclohexane

The photochemistry of phenyldiazomethane in cyclohexene (cyclohexene-d10) and cyclohexane (cyclohexane-d12) was studied.The chemistry observed was found to be entirely consistent with singlet rather than triplet phenylcarbene reactions.Small (1.9-2.1) isotope effects to CH insertion were observed at 25 deg C that increased on cooling.Cooling to very low temperature (-196 deg C) reduced the isotope effect.The results are discussed in terms of the hardness of the polycrystalline solid matrix.

Synthese d'olefines et de polyenes par doublement d'anions α-sulfonyles en presence de sels de nickel

The lithium or magnesium derivatives of allyl, benzyl and alkyl sulphones are converted efficiently by a catalytic amount of nickel(II) acetylacetonate into symmetrical olefins in THF at 60 deg C.Thus, phytoene was obtained in a 70percent yield from geranylgeranylsulphone.
