Ethylene Polymerization by Novel, Easily Accessible Catalysts Based on Nickel (II) Diazene Complexes

Additional [D 5 ]pyridine caused formation of another paramagnetic species (presumably 1 c·2 Py, see Figure 3C), which, under high pyridine/Ni ratios (ca. 100:1), became the

The different grey scales for different particles can be easily rationalized by different viewing angles: If the disc-like particles are nearly parallel to the electron beam,

Driven by our interest to conduct ethylene polymerization in highly polar aqueous media, 13 we have shown that a similar and easily accessible κ 2 -(N,O)-salicylaldiminato nickel

Substituent Effects in ( κ 2 -N,O)Salicylaldiminato Nickel(II)-Methyl Pyridine Polymerization Catalysts: Terphenyls Contolling

Ethylene polymerization was carried out under atmospheric pressure in toluene in a 500 mL glass reactor equipped with a mechanical stirrer.. Toluene (200 mL) was introduced into

By contrast to polymerization in the absence of water, or polymerization in aqueous suspension, in the highly disperse emulsion system incorporation of butadiene occurs in a

Much to our delight we found that most of the differently modified G quadruplexes (Scheme 2) were able to catalyze the aldol reaction between acetone and 1 at very low concentra-
