✦ Synopsis

The new 1,1,2,2-tetraphenyl 1,2-digermyldilithium compound (2) IS prepared in high yield by metallation of the correspondmg aryldihydrodigermane (1) with t-BuLi in THF. It is characterized by r3C NMR spectroscopy and by alkylation with methyl iodide. Some nucleophilic substitution reactions are reported: compound 2 reacts with MesCOCl to give a new digermyldiketone [Ph,(MesCO)Ge], (8). Its germylation reaction with several alkyl methoxygermanes or -digermanes constitute a convenient way for synthesizing cyclopolygermanes (3,4 or 6 rings). Its reaction with trans-CI,Pt(PEt,),

leads to a mixture of the expected cyclic complex 12 and its corresponding oxide 13.

## Abstract The reverse atom‐transfer radical polymerization (RATRP) technique using CuCl~2~/2,2′‐bipyridine (bipy) complex as a catalyst was applied to the living‐radical polymerization of acrylonitrile (AN). 1,1,2,2‐Tetraphenyl‐1,2‐ethanediol (TPED) was first used as the initiator in this copper‐
