The examination of the palladium catalysed arylation reactions of mono-iodo derivatives of the phenyl and benzyl esters of benzoic acid, phenylacetic acid and dehydrocinnamic acid has resulted in the formation of benzo[c]chromen-6-ones, unexpected cinnamate and succinate products and diphenyl dimers. Many of these products can be rationalised as arising from novel cyclic ArPd(II)-enolate intermediates, formed by intramolecular C-H activation by ArPd(II). Crown Copyright © 2007.

Planetary science studies the origin of the solar system and whether life exists on other planets. It has the potential to change the way we vie the world and our selves. Planetary science offers a cost effective means for Australia to participate in a pretigious international arena. Space engages the public's imagination and can inspire young people in tehir choice of careers. Students gain a strong foundation in mathematics, fundamental sciences and advanced technology, thereby fostering creativity and promoting a culture of innovation. Despite the absence of a national space program, Australian planetary scientists have strong international reputations in cosmochemistry, planetary geology and planetary geophysics.
