Grignard reagents may be used to prepare other organometallic reagents, for example, ethylmagnesium bromide reacts with cadmium chloride to yield diethylcadmium.
2CH3CH2MgCl + CdCl2 yields (CH3CH2)2Cd + 2MgCl2
Indicate the product of the following reactions and name the organometallic product.
(A) 4CH3MgCl + SiCl4 yields ?
(B) 2C6H5MgCl + HgCl2 yields ?
