Abstract (en)
[origin: WO2020021187A1] Method for preparing a compound having an alkoxysilyl group of formula (I), wherein X represents –O- or -NR4- with R4 = H or C1-C4 alkyl; R1 is a radical having from 1 to 20 carbon atoms; R2 and R3 are a C1-C4 alkyl radical; p is an integer equal to 0, 1 or 2; comprising a cross metathesis reaction in the presence (i) of a compound having a group of acrylate type and of formula: -X(C=O)-CH=CH2, (ii) of an α-olefinic silane of formula (II): and (iii) of a metathesis catalyst chosen from GRUBBS catalysts and 2nd generation HOVEYDA-GRUBBS (HG2) catalysts. 2) Compound having said alkoxysilyl group, obtained by the method 1).
