A process can prepare a 3-glycidyloxypropylalkoxysilane of formula (I), (R')O&#x2014;(CH)&#x2014;Si(OR)(I), where R groups are independently a methyl or ethyl group and R&#x2032; represents an HC(O)CHCH&#x2014; group. The process includes reacting (i) a functionalized alkene of formula (II), (R&#x2032;)O&#x2014;CH(II), where R&#x2032; represents an HC(O)CHCH&#x2014; group, with (ii) at least one hydroalkoxysilane of formula (III), HSi(OR)(III), where R groups are independently a methyl or ethyl group. The reacting takes place in the presence of (iii) a Karstedt catalyst or a catalyst having hexachloroplatinic acid as a homogeneous catalyst, and (iv) 2-ethylhexanoic acid, isononanoic acid, or both. The process further includes obtaining a product of the reacting.
