Other five diesters were synthesized from all-trans-retinoic a.

8%, after vacuum distillation, the yield of diester was 48.

The internal electron donor compounds such as monoester, diester and diether compounds in Ziegler-Natta catalyst system were reviewed with an emphasis on the diether without external electron donors.

The content determination methods of monoester,di-ester,tri-ester and phosphoric acid in mixed phosphate are introduced.

A type of living radical polymerization based on reversible chain transfer,especially,reversible addition-fragmentation chain transfer (RAFT)radical polymerization using dithioester compounds as chain transfer agents developed by Rizzardo and his coworkers lately was reviewed with 25 references.

Using 2 methyl cyclopentane 1,3 dione as start material, the title bicyclolactone was synthesized via alkylation, Wittig Horner reaction, catalytic hydrogenation, sodium borohydride reduction and acid catalyzed intramolecular transesterification.
