The two-fold reaction benchmark applied to the copper catalyzed assembling of 1,w-difunctional hydrocarbon chains
Long-chain hydrocarbons carrying vinyl groups, chlorine atoms or oxygen functions at the terminal positions can be prepd. with excellent yields by copper mediated coupling of alkyl tosylates and Grignard reagents. E.g., Li2CuCl4 catalyzed the coupling of C ...
1991Selective syntheses with organometallics. Part XI. An efficient synthesis of a,b-unsaturated aldehydes by a four-carbon unit extension of Grignard reagents
Oxirane I, prepd. by epoxidn. of (EtO)2CHCH2CH:CH2, reacted with Grignard reagents in the presence of catalytic CuBr to give 78-92% b-hydroxyacetals (EtO)2CHCH2CHR1OH [II; R1 = CH2CMe3, CH2CHMeEt, pentyl, CH2CH2CMe:CH2, CH2Ph, CH2CH2Ph, (CH2)7OR2; R2 = tet ...
1984Prescriptions and ingredients for controlled carbon-carbon bond formation with organometallic reagents
Merits and drawbacks of known C-C linking procedures, such as condensation, addn., and isomerization reactions, are outlined. Two novel methods are discussed in more detail: the Cu-catalyzed alkylation of Grignard reagents, and reactions with allylpotassiu ...
