## Abstract Neodymium tris(2βethylhexylphosphonate)βtriisobutylaluminumβwater system was investigated as a catalyst in ethylene oxide and propylene oxide copolymerization. Random copolymers of ethylene oxide and propylene oxide were obtained with high yield and high molecular weight in a short reac
## Abstract Alkylation of lanthanidocene chloride complexes was performed with BuLi, Mg(Bu)(Oct), or an equimolar mixture of BuLi and AlH(__i__Bu)~2~. In the case of the latter, chain transfer reactions were observed between neodymium and aluminium, and higher activities were obtained. The use of t
