Controlled oligomerizations

Feldman et a .210 211 and Wulff et ul v have examined other forms of template controlled oligomerization of acrylic monomers. The template (23) has initiator and transfer agent groups attached to a rigid template of precisely defined structure.210 "11 Polymerization of MMA in the presence of 23 gave a 3 unit oligo(MMA) as ca 66% of the polymeric product. The stereochemistry of the oligomer was reported to be different" from that of atactic PMMA. [Pg.439]

As the ladderanes have rigid rodlike structures consisting of C-C a bonds, they have been used as spacer for electron-transfer reactions32,33 and as templates for controlling oligomerization.34... [Pg.137]

Further studies on the controlled oligomerization of isoprene (5) have shown that treatment with a nickel alkoxide catalyst provides tran5-/3-farnesene (6) in -60% yield. ... [Pg.81]
