Sodium trihydridodimethyldizincate

Zn/Cu + CHjI CH3ZnI + Cu 2CH3ZnI + 3NaH Na[Zn2(CH3)2H3]-xTHF + 2NaI 

---

The reaction described here of methylzinc iodide with sodium hydride, to produce Na[Zn2(CH3)2H3], may be pictured as a combination of the two reaction types named above. Unlike many hydride preparations, the synthesis of sodium trihydridodimethyldizincate(l —) is easily performed using ordinary Schlenk-type bench-top techniques and commercially available starting materials.4 Sodium trihydridozincate( 1 —) is easily prepared by exposing Na[Zn2(CH3)2H3]-xTHF to high vacuum.4...
