note
-
1H NMR spectrum of 11 was similar to the one of 9 but it presented an extra singlet at 2.52 ppm, assignable to the acetylenic hydrogen of the second triple bond.

note
-
1H NMR spectrum of this fraction presented different signals between 0.45 and 0.65 ppm which shows the presence of more than one product with a methyl group on the silicon atom, as well as two massifs between 1.50-1.90 and 2.12-2.52 ppm and a singlet at 4.72 ppm. These signals could be attributed to products of general structure:{A figure is presented}

note
-
1H NMR spectrum of the crude product showed the total conversion of the starting material and presented the characteristic signals of this family of products, notably two doublets at 5.14 and 5.45 ppm due to the olefinic protons. In LRMS an ion at m/z = 140, which correspond to the formula weight of the desired product, was obtained.
