The chemistry of metalloid cluster compounds for Al, Ga and In dominate current Group 13 chemistry; a review by Schnepf and Schnöckel summarizes the situation for Al and Ga.13bThe first direct observation of radicals by EPR in the activation of a Zeigler–Natta system is both interesting and important for our understanding of these catalysts.50bFor gallium and indium chemistry, a highlight very much in tune with the green chemistry movement, is the report of the first aqueous preparation of high yield, relatively monodisperse, well crystallized GaP and InP nanocrystallites, exhibiting pronounced quantum confinement.59Whilst they have had to be relegated to ESI, the increasing interest in indium for Barbier-Grignard type organic syntheses in aqueous media has a green complexion and there are the first signs of similar developments for aqueous gallium chemistry.110bNew work on the two-electron transfer for Tlaq3+/Tlaq+with electrochemical evidence for [Tl(ii)–Tl(ii)]4+is a major highlight for thallium chemistry.142The synthesis and structure of [In(ii)–In(ii)]4+is also notable.129
