Group 2 elements beryllium chloride

Bollard and Butler (1966) in their discussion of functional elements include several others in addition to the above four. They state that fluorine, iodine, and selenium fall in this class for in some plant species they are metabolized, forming definite organic compounds. Bromine, rubidium, and strontium are also placed in this class because they exert a sparing effect on the utilization of chloride, potassium and calcium. Cobalt may perform that same function. They state further that our knowledge of the beneficial effects produced by aluminum, beryllium, and barium are not as yet adequate to justify including these in the group of functional elements. Further research will probably add other elements to this group. 

Various combinations of basic beryllium acetate, propionate, and benzoate were reacted with the acid chlorides of adipic, sebacic, /8-ethyladipic, tere-phthalic, and isophthalic acids. Solution viscosities of the products (in toluene) were very low. Elemental analytical data tended to confirm this fact by showing the presence of inordinate amounts of end groups.
