Addition of Organomagnesium Halides to C = C Bonds, XVII. Reactions of Organomagnesium Halides with (Trimethylsilyl)ethyleneEthyl- (2), isopropyl- (3), and the 2-alkenylmagnesium halides 4 and 15 add with 〉 95% regioselectivity to the C = C bond of (trimethylsilyl)ethylene (1) to give the 1:1 adducts 5 - 7 and 16 which upon hydrolysis are converted into the (trimethylsilyl)hydrocarbons 8 - 10 and 17. In the case of 15, addition is accompanied by inversion of the 2-butenyl to the 1-methylallyl group to give 16.
Notes:
Ethyl- (2), Isopropyl- (3) und die 2-Alkenylmagnesiumhalogenide 4 und 15 addieren sich zu 〉 95% regioselektive an die C = C-Bindung in (Trimethylsilyl)ethylen (1) zu den 1:1-Addukten 5 - 7 und 16, aus denen durch Hydrolyse die (Trimethylsilyl)kohlenwasserstoffe 8 - 10 und 17 erhalten werden. Bei 15 erfolgt bei der Addition Inversion des 2-Butenyl- zum 1-Methylallyl-Rest unter Bildung von 16.
