A chemical compound of the formula (I) in which R1 and R2 are independently selected from C1±C3 alkyl, or R1 and R2 together with the silicon atom to which they are joined form a 5 to 6 membered ring, the ring, apart from the silicon atom, consisting completely of hydrocarbon atoms, and their preparation via hydroformylation of divinylsilanes such as dialkyldivinylsilane, dichlorodivinylsilane, or 1,1-divinylsilolane with subsequent aldol condensation and Grignard reaction. The compounds of formula I are useful in fragrance applications for incorporation into fine and functional fragrances. |
