Vapourization of Metals and Codeposition with Reactants

Further fields of study were opened up when techniques were developed for the deposition of vapours of less volatile metals on cold surfaces, allowing the formation of pure metal-layers of varying thickness [4]. 

Ground-State Magnesium. This led to investigations [5] of chemical reactions with ground-state magnesium, Mg in 1972. 

Codeposition of this metal with a large excess of water ( 100 1) gave hydrogen in more than 90% yield after warming up  

With ammonia the yield of hydrogen was less than 3%  

When magnesium was codeposited with organo halides, solvent-free Grignard reagents were obtained. The yields (determined by hydrolysis) for each of the following hahdes were
