Organozinc

The intramolecular insertion of an internal alkyne into an aryl or alkenyl halide 727 generates aryl- or alkenylpalladium as an intermediate, which is trapped with an organozinc or organostannane to give 728. Overall cis addition to the alkyne takes place[595,596]. The reaction of the alkenylstannane 730 with the 2-bromomethylfuran 729 is used for the introduction of a prenyl group[597]. [Pg.236]

The reaction of 2,3-butadienyl acetate (843) with soft carbon nucleophiles such as dimethyl malonate gives dimethyl 2,3-butadienylmalonate (844)[520]. On the other hand, the reaction of the 2,3-butadienyl phosphate 845 with hard carbon nucleophiles such as Mg and Zn reagents affords the 2-allcyl-1,3-butadiene 846[520,521]. The 3-methoxy-1,3-butadiene 848 is obtained by the reaction of the 2-methoxy-2,3-butadienyl carbonate 847 with organozinc reagent. [Pg.405]

The 2-(l-alkynyl)oxirane 78 reacts with an organozinc reagent yielding the /9-allenylic alcohol 79[35]. [Pg.464]

Blanchard and Simmons suggested that the stable organozinc intermediate obtained in this reaction is probably bis-(iodomethyl) zinc zinc iodide (1). [Pg.108]

The reaction of CF3I and CgFjI with dialkylzmc in the presence of a Lewis base, such as diglyme or pyridine, quantitatively gives the corresponding fluori-nated organozinc complexes [32] (equation 23) When Rf is C2F5 or iso CjF-j, the pure zinc complexes are not isolated... [Pg.675]

Organozinc reagents aie not nearly as reactive towaid aldehydes and ketones as Grig-nai d reagents and organolithium compounds but are intermediates in certain reactions of alkyl halides. [Pg.604]

An organozinc compound that occupies a special niche in organic synthesis is iodo-methylzinc iodide (ICH2ZnI). It is prepared by the reaction of zinc-copper couple [Zn(Cu), zinc that has had its surface activated with a little copper] with diiodomethane in diethyl ether. [Pg.604]

Design of chiral catalysis and asymmetric autocatalysis for diphenyl-(l-methyl-pyrrolidin-2-yl) methanol-catalyzed enantioselective additions of organozinc reagents 97YGK994. [Pg.247]

The study of the Schlenk equilibrium for organozinc compounds represents a major chapter in the understanding of these reagents in general [26]. Before elaborating the studies on zinc carbenoids, it is appropriate to briefly review the definitive investigations on organozinc halides themselves. [Pg.93]

Eor ethylzinc chloride, CH3CH2ZnCl, and ethylzinc bromide, CH3CH2ZnBr, there is a linear relationship between the observed chemical shift and the ratio of ethylzinc halide to diethylzinc. Extrapolation of these lines to x=l (mol fraction of CH3CH2Z11X) gives predicted values for the average chemical shift that closely match those measured for these species. This indicates that for these two organozinc halides, the Schlenk equilibrium lies heavily on the side of the ethylzinc halide in toluene. However, in the case of ethylzinc iodide, CH3CH2ZnI, there is a... [Pg.94]
