Fragrant silanes having the formula: (R1O)a(R2O)b(R3O)c(R4)d(R5)eSiR6 where R1, R2 and R3 are derived from the group of alcohols consisting of R1OH, R2OH and R3OH wherein R1OH, R2OH and R3OH are fragrant alcohols or alternatively R1, R2 and R3 are derived from the group of fragrant esters, ketones, or aldehydes having the structure: R7-CH2(C=O)-R8 wherein the fragrant ester, ketone or aldehyde is capable of exhibiting the enol form of the carbonyl moiety under reaction conditions, with R4 and R5 selected from the group consisting of monovalent hydrocarbon radical having from one to forty carbon atoms and monovalent alkoxy radicals having from one to forty carbon atoms, R6 a two to forty atom monovalent unsaturated hydrocarbon radical containing a terminal olefinic or acetylenic moiety where the subscript a has a value ranging from 1 to 3 and the subscripts b, c, d, and e have values ranging from 0 to 2 subject to the limitation that a+b+c+d+e=3; R7 is selected from the group consisting of hydrogen and monovalent hydrocarbon radicals having from one to one hundred carbon atoms and R8 is selected from the group consisting of hydrogen and monovalent hydrocarbon radicals having from one to one hundred carbon atoms.
