Abstract

Allylboronic esters are obtained in good yield by the reaction of allyltrialkyltin derivatives with 2-chloro-l,3,2-dioxaborolane. In the case of tributylprenyltin 4(S)-7-triethylstannyl-p-menthene and tri-n-butylcrotyltin the boron/tin-exchange leads to allylboronates without apparent allyl inversion.

Zusammenfassung

Allylboronsäureester werden in guten Ausbeuten durch die Umsetzung von Allyl-trialkyl-zinn-Derivaten (VI) mit 2-Chlor-1,3,2-dioxaborolan (VII) erhalten. Im Fall von XI, XIII und XVI führt der Bor/Zinn-Austausch zu Allylboronaten ohne ersichtliche Allyl-Inversion.

NMR study of the exchange reactions between allyltrialkyltin compounds and lewis acids part 1. Exchanges with boron tribromide and trifluoride and titanium tetrachloride
1989, Inorganica Chimica Acta
Reactions between BX₃ (X = F or Br) and TiCl₄ with R¹CHCHCH₂SnR₃ [I, R = Me, Bu or cyclohexyl(Cy); R¹ = H or Me] have been studied by NMR spectroscopy. Allyl group-bromine exchanges occur between I and BBr₃ at −60 °C; at higher temperatures (c. −10 °C) I (R = Me or Bu but not Cy) reacts further to give R₂SnBr₂. No allyl group-fluorine exchange products were detected from the reaction between I and BF₃·Et₂O below −20 °C. However, at 25 °C I (R = Me, R¹ = H) reacts readily with BF₃·Et₂O, the predominant soluble tin product being Me₄Sn. Compounds I and TiCl₄ at 30 °C rapidly produce R₃SnCl and [RCHCHCH₂]TiCl₃.
The silyl-cupration and stannyl-cupration of allenes
1989, Tetrahedron
The stoichiometric silyl-cupration of allene 7, followed directly by treating the intermediate cuprate with a proton, with a range of carbon electrophiles, and with chlorine gives the vinylsilanes 8–13. Alternatively, when iodine is the electrophile, the product is the vinyl iodide 16. This can then be metallated and treated with a proton or a range of
carbon electrophiles to give the allylsilanes 18–21. More-substituted allenes also undergo silyl-cupration followed by protonation, phenylallenes giving vinylsilanes, and alkylallenes giving, on the whole, allylsilanes. Stoichiometric stannyl-cupration of allenes takes place, with similar but less reliable regiocontrol to that of the corresponding silyl-cupration.
