Zusammenfassung: | The present invention relates to a composition containing: (a) a hydrosilylation catalyst comprising a metal-ligand complex; and (b) an inhibitor of the catalyst, wherein the inhibitor differs from the ligand of the metal-ligand complex and is represented by chemical formula (I), X-CHR-CO-Y. In the formula, -X represents -NO_2, -S(=O)R, or R^c_2R^aC-CO-; Y represents 2-furyl, -S(=O)R, -CN, -NO_2, or -CR^b_xR^d_(3-x); R^a and R^b is independently selected from the group consisting of -O-R, -O-CO-R, -CO-O-R, 2-furyl, -S(=O)R, -CN, -NO_2, -F, -Cl, and -Br; each of R is independently selected from the group consisting of -H, optionally fluorinated C_1-C_8-alkyl, -F, -Cl, and -Br; each of R^c and each of R^d is independently selected from the group consisting of -H, optionally fluorinated C_1-C_8-alkyl, -F, -Cl, and -Br; and x is 0 or 1.
본 발명은 (a) 금속-리간드 착물을 포함하는 하이드로실릴화 촉매, 및 (b) 촉매의 억제제로서, 금속-리간드 착물의 리간드와는 상이하고, 하기 화학식 (I)로 표현되는 억제제의 성분들을 함유한 조성물에 관한 것이다: X-CHR-CO-Y(I), 상기 식에서, -X는 -NO2, -S(=O)R, 또는 Rc2RaC-CO-를 나타내며; Y는 2-푸릴, -S(=O)R, -CN, -NO2, 또는 -CRbxRd3-x를 나타내며; Ra 및 Rb는 -O-R, -O-CO-R, -CO-O-R, 2-푸릴, -S(=O)R, -CN, -NO2, -F, -Cl, 및 -Br로 구성되는 군으로부터 독립적으로 선택되며; 각 R은 -H, 선택적으로 불소화된 C1-C8-알킬, -F, -Cl, 및 -Br로 구성되는 군으로부터 독립적으로 선택되며; 각 Rc 및 각 Rd는 -H, 선택적으로 불소화된 C1-C8-알킬, -F, -Cl, 및 -Br로 구성되는 군으로부터 독립적으로 선택되며; x는 0 또는 1이다. |
