摘要：
Pivaloylacetonates of alkaline-earth elements with composition M(Pa) 2·nH2O (n = 1, M = Sr, Ca; n = 0, 2, M = Ba) were synthesized and studied by IR and thermal analysis; their solubilities and volatility were estimated. It was found that the volatility changes regularly in the series M(Acac)2-M(Pa)2-M(Thd)2 (HAcac is acetylacetone, HThd is dipivaloylmethane). The replacement of one methyl radical by the tert-butyl radical when going from acetylacetonates to pivaloylacetonates was shown to noticeably increase the volatility only for Sr(Pa)2·H2O. Complexes of barium pivaloylacetonate with tetraglyme and o-phenanthroline were synthesized and characterized.
