Magnesium reactions

Magnesium, reaction with 1 chlorobu-tane in methylcyclohexane, 47, 113... 

Tetramethyl-l,3-disilacyclobutane had been prepared earlier by Knoth and Lindsey [10], but a multistep synthesis was involved which was not generalizable to the synthesis of Si-functional 1,3-disilacyclobutanes. The reaction shown in eq. 4, provided it is carried out in the right way, represents a good, general route to 1,3-disilacyclobutanes. This reaction was reported first by Muller and his coworkers [11]. In this work, diethyl ether was used as reaction solvent and the product yield was only around 4%. Somewhat better yields were obtained" by Russian workers [12], but it was the detailed studies of the (chloromethyl)chlorosilane/ magnesium reaction by Kriner [13] which provided a good synthesis of...

Magnesium. Reaction to give Grignard compounds may be violent.2... 

Diphenyl-1,3-butadiene has been one of the most reactive conjugated dienes towards metallic magnesium. Reaction of this diene with Rieke magnesium affords (l,4-diphenyl-2-butene-l,4-diyl)magnesium 2, which can be treated with various electrophiles, as shown in Scheme 3.
