Valorisation of vegetable oils via metathesis reactions on solid catalysts: Cross-metathesis of methyl oleate with 1-hexene

Abstract The activity and selectivity of silica-supported Hoveyda-Grubbs (HG) complex for the cross-metathesis of methyl oleate with 1-hexene to obtain 1-decene, methyl 9-tetradecenoate, 5-tetradecene and methyl 9-decenoate were studied in a batch reactor. The HG complex loading was varied between 0.87 and 11.6 wt%. Competitive secondary reactions were the self-metathesis of methyl oleate and the self-metathesis of 1-hexene. The yield to cross-metathesis products (ηC-M) was 47% when a 1-hexene/methyl oleate reactant ratio (RC6/MO) of one was employed. The ηC-M value increased with increasing 1-hexene initial concentration, reaching 87% for RC6/MO = 7. The selectivity to terminal olefins also increased at the expense of internal olefins among the cross-metathesis products when the concentration of 1-hexene was increased.

Tandem application of C-C bond-forming reactions with reductive ozonolysis

Several variants of reductive ozonolysis, defined here as the in situ generation of aldehydes or ketones during ozonolytic cleavage of alkenes, are demonstrated to work effectively in tandem with a number of C-C bond-forming reactions. For reactions involving basic nucleophiles (1,2- addition of Grignard reagents, Wittig or Horner-Emmons olefinations, and directed aldol reactions of lithium enolates), the one-pot process offers a rapid and high-yielding alternative to traditional two-step protocols.

Iron thiolate complexes: Efficient catalysts for coupling alkenyl halides with alkyl grignard reagents

Ironing out the kinks: Efficient new catalytic systems based on iron thiolates are described for the iron-catalyzed cross-coupling of alkyl Grignard reagents with alkenyl halides (see scheme). The reaction is highly chemo- and stereoselective. With this new procedure, the use of N-methylpyrrolidone as a co-solvent is no longer required. Copyright

Reaction of trialkyl(dibromomethyl)silanes or 1,2-bis(dibromomethyl)benzene with triorganomanganates. A facile and selective synthesis of alkenylsilanes and 1,2-diaryl-1,2-dihydrobenzocyclobutenes

Treatment of trialkyl(dibromomethyl)silanes with trialkylmanganates, derived from manganese(II) chloride and three molar amounts of Grignard reagents or alkyllithiums, provided (E)-1-trialkylsilyl-1-alkenes with high stereoselectivity in good yields. The reaction of trialkyl(dibromomethyl)silanes with alkylmagnesium halides proceeded in the presence of a catalytic amount of manganese(II) chloride. Treatment of 1,2-bis(dibromomethyl)benzene with triphenylmanganate gave 1,2-diphenyl-1,2-dihydrobenzocyclobutene.

Libraries via Metathesis of Internal Olefins

The cross-metathesis of internal olefins is applied for the combinatorial synthesis of small organic molecules; this reaction is conveniently carried out in neat olefin (oleic-acid derivatives) and requires only 0.001 equiv. of [Ru(CHPh)Cl2(PCy3)2] as catalyst (Cy = cyclohexyl).

Cobalt-catalyzed alkenylation of zinc organometallics

Organozinc halides and diorganozincs undergo cross-coupling reactions with either E- or Z-alkenyl iodides in the presence of catalytic amounts of Co(acac)2 or Co(acac)3 in THF:NMP at 55°C leading to polyfunctional alkenes with retent

Highly stereo and chemoselective iron-catalyzed alkenylation of organomagnesium compounds

In the presence of Fe(acac)3, Grignard reagents react readily with alkenyl halides (X = I, Br or Cl) in a THF/NMP mixture to give the cross-coupling products in high yields with an excellent stereoselectivity (≤99.5%). The scope of the reaction is very broad since a vast array of functional groups are tolerated (esters, nitriles, aromatic or aliphatic halides and even ketones). The procedure reported herein is an interesting alternative to the classical Pd- or Ni-catalyzed reactions, especially for preparative organic chemistry.
