Abstract

The beryllium chelates of 2-hydroxy-3-methylacetophenone, 2-hydroxy-3-isopropylisobutyrophenone and 2-hydroxyacetophenone, and the copper- and nickel chelates of the ketimine derivatives of 2-trifluoroacetylphenol and 2-hydroxyisobutyrophenone in addition to the above o-acylphenols were synthesized. The thermal stability and relative volatility of these chelate compounds, measured by means of a thermogravimetric method, were found to be strongly increased by introduction of bulky alkyl or trifluoromethyl groups.
