Stabilized and persistent allenylketenes

Photolyses of 2,3-bis(trimethylsilyl)-substituted methylenecyclobutenones 22-26 give essentially quantitative conversion to the allenylketenes 28-32 which have been isolated as long-lived species at room temperature. As predicted by molecular orbital calc

A convenient synthesis of perfluoroalkylated allylic sulfides

Perfluoroalkylated allylic sulfides can be synthesized by the reaction of thiophenoxymethyl lithium with fluorinated β-oxoalkylphosphonium salts in 51percent-72percent yields. - Keywords: Synthesis; Perfluoroalkylated allylic sulfides; NMR spectroscopy; I

Thermal rearrangements of allenes. Synthesis and mechanism of cycloaromatization of π and heteroatom bridged diallenes

The synthesis and thermal rearrangement of several π and heteroatom bridged diallenes has been investigated. o-Diallenylbenzenes 5, 14, 24 and bis(γ,γ-dimethylallenyl) ether 8 were prepared by addition of dibromocarbene to the corresponding divinyl precursor, followed by treatment of the resulting dibromocyclopropane derivative with methyllithium. Bis(γ,γ-dimethylallenyl) sulfide 10 was generated by reaction of (γ,γ-dimethylallenyl)lithium with sulfur dichloride, while the corresponding selenides 12 and 16 were synthesized by an SN2′ reaction of sodium selenide with α,α-dimethylpropargyl bromide. All diallenes prepared display a remarkable thermal reactivity and undergo a facile cycloaromatization. Gentle heating of diallenes 5, 14, 12, and 16 gave the naphthalene derivatives 6 and 15 and selenophene derivatives 13 and 17, respectively, in practically quantitative yields. Diallenes 8, 10, and 24 underwent spontaneous cyclization during preparation yielding furan 9, thiophene 11, and naphtho[b]cyclobutane 25, respectively. A kinetic study of the rearrangement and measurement of the kinetic isotope effect using diallenes 5, 14, 12, and 16, revealed that the cyclization is a two-step process. The first and rate-determining step is an electrocyclic reaction yielding as intermediates ω-xylylenes 20 and 21, while the second and more rapid step entails a [1,5]hydrogen transfer.

A Novel Synthesis of α-Fluoroalkylvinyl- or α-Fluoroepoxyalkyl-phosphonate

α-Fluoroalkylvinyl- or α-fluoroepoxyalkyl-phosphonates can be synthesized by the reaction of diethyl lithium phosphite with fluorinated β-oxoalkylphosphonium salts, depending upon the α-substituents R1 and R2 in the alkylidene moiety of the phosphorane us

A Novel One-pot Synthesis of Fluoroenynes

A novel one-pot synthesis of fluoroenynes via eliminative nucleophilic addition of β-ketophosphonium salts to acetylide anions is described.
