Ten phenoxysilanes with various organic groups on the silicon were prepared and their 1H and 13C NMR spectra recorded. The groups on the silicon had only a small effect on the proton and carbon chemical shifts.
LE REARRANGEMENT DE CLAISEN EN SERIES SILICIEE ET GERMANIEE: SILAETHYLENE ET GERMAETHYLENE

Thermolysis of silicon and germanium isologues of of allyl aryl ethers via transient metal ?-bonded intermediates leads to aromatic Claisen type rearrangement.Para-Claisen type reaction is not observed when the aromatic ring is ortho-disubstituted.In that
LE PROBLEME DE LA CONJUGAISON A TRAVERS UN ATOME DE SILICIUM ?-LIE DANS LES SYSTEMES SILA-2 BUTADIENIQUES

The chemical behaviour of sila-2 butadienes, formed as transient intermediates either by thermolysis or by photolysis of various 1-vinylsilacyclobutanes, was studied with respect to hydroxylated compounds of different pKa values.Two mechanisms can explain the nature of the products obtained on the co-thermolysis of the cyclic compounds with phenol, one with 1-silacyclobut-1-ene intermediate and the other involving an allylic silicenium cation.In both hypothetical mechanisms, the 2-silabutadienes behave as a conjugated system since they lead either to cycloaddition or to (1,2)- and (1,4)-electrophilic addition.This evidence for a conjugation phenomenon through a silicon atom is supported by the calculation of the delocalisation energies of butadiene and 2-silabutadiene.
