Functionalized silicon compounds

A process for preparing a functionalized carbo-silicon compound comprising

• contacting, in the presence of a hydrosilation catalyst, under hydrosilation promoting conditions, a silicon reactant of Structure I with an unsaturated olefin reactant of Structure III, wherein:
• the compound of Structure I has the formula:
• wherein
• “a” is 1, 2, or 3 and “b” 0, 1, 2, or 3, selected such that “a”+“b” is less than or equal to 4
• “Z” is a hydrolyzable substituent,
• “R1” is independently selected from the group consisting of:
• (i) silicon-based moieties selected from the group consisting of carbosilanes, siloxanes, carbosiloxanes, and polymeric cognitors thereof which are optionally substituted with one or more hydrolyzable functional groups on one or more silicon atoms thereof;
• and (ii) saturated or unsaturated, linear, branched, or cyclic, aliphatic or aromatic, hydrocarbon moieties which are optionally substituted on any carbon thereof with one or more members selected independently for each occurrence from the group consisting of alkyl, aryl, hydroxyl, alkoxy, and halogen moieties;
• wherein a plurality of R1 substituents may be portions of a cyclosiloxane structure;
• and wherein the compound of Structure III has the formula:
• wherein
• “n” is 0 or 1,
• “Q” is a second functional group characterized by having a substantial potential to impede a hydrosilation reaction,
• “A” is selected from —[CH2]c—S—[CH2]d, —[CH2]c—O—[CH2]d, or —[CH2]c—N(R4)—[CH2]d, wherein “c” is an integer including 0, “d” is at least one, and R4 is an alkyl moiety having less than three carbon atoms,
• R2 is selected from the group consisting of saturated or unsaturated, linear, branched, or cyclic, aliphatic or aromatic, hydrocarbon moieties and a moiety of the structure of Structure IV:
• and
• R3 is selected from the group consisting of saturated or unsaturated, linear, branched, or cyclic, aliphatic or aromatic, hydrocarbon moieties,
• provided that only one of R3 and R4 is selected to be an unsaturated moiety.

A compound having the structure of Structure V:

• wherein
• “a” and “b” are integers, including zero, selected independently such that “a”+“b” is equal to or less than 3;
• “Z” is a hydrolyzable substituent;
• “Q” is functional group characterized by having a substantial potential to impede a hydrosilation reaction;
• “A” is selected from —[CH2]c—S—[CH2]d, —[CH2]c—O—[CH2]d, or —[CH2]c—N(R4)—[CH2]d, wherein “c” is an integer including 0, “d” is at least one, and R4 is an alkyl moiety having less than three carbon atoms;
• “n” is 0 or 1;
• “R1” is selected from the group consisting of:
• (i) silicon-based moieties selected from the group consisting of carbosilanes, siloxanes, carbosiloxanes, and polymeric cognitors thereof which are optionally substituted with one or more hydrolyzable functional groups on one or more silicon atoms thereof;
• and (ii) saturated or unsaturated, linear, branched, or cyclic, aliphatic or aromatic, hydrocarbon moieties which are optionally substituted on any carbon thereof with one or more members selected independently for each occurrence from the group consisting of alkyl, aryl, hydroxyl, alkoxy, and halogen moieties;
• wherein a plurality of R1 substituents may be portions of a cyclosiloxane structure;
• “R2” is selected from the group consisting of saturated or unsaturated, linear, branched, or cyclic, aliphatic or aromatic, hydrocarbon moieties and a moiety of the structure of Structure IV:
• and
• “R3” is selected from the group consisting of saturated or unsaturated, linear, branched, or cyclic, aliphatic or aromatic, hydrocarbon moieties,
• provided that only one of R3 and R4 is selected to be an unsaturated moiety.
