Usage

Description

DIMETHYL 2,6-DIBROMOHEPTANEDIOATE is an organic compound that is characterized by the presence of two bromine atoms attached to a heptanedioate backbone. It is a versatile chemical intermediate that can be utilized in various chemical reactions and synthesis processes.

Uses

Used in Polymer Synthesis:
DIMETHYL 2,6-DIBROMOHEPTANEDIOATE is used as a precursor in the preparation of difunctional poly(n-butyl acrylate) (pBA) macroinitiator. This macroinitiator is essential for the synthesis of well-defined polymers with controlled molecular weights and architectures, which can be further utilized in various applications such as drug delivery, coatings, and adhesives.
Used in Polymer Chemistry Research:
DIMETHYL 2,6-DIBROMOHEPTANEDIOATE is used as an initiator for the synthesis of dibromo-terminated polystyrene via atom transfer radical polymerization (ATRP). ATRP is a powerful and versatile technique for the synthesis of polymers with controlled molecular weights, narrow molecular weight distributions, and well-defined end-groups. The dibromo-terminated polystyrene can be employed as a building block for the preparation of block copolymers, star polymers, and other complex polymer architectures.
Used in Reversible Addition-Fragmentation chain Transfer (RAFT) Agent Synthesis:
DIMETHYL 2,6-DIBROMOHEPTANEDIOATE is used in the preparation of polytrithiocarbonate, which serves as a Reversible Addition-Fragmentation chain Transfer (RAFT) agent for radical polymerization reactions. RAFT is an efficient and robust method for the synthesis of polymers with controlled molecular weights, narrow molecular weight distributions, and functional end-groups. The RAFT agent derived from DIMETHYL 2,6-DIBROMOHEPTANEDIOATE can be employed in the controlled polymerization of various monomers, enabling the synthesis of a wide range of polymeric materials with tailored properties for specific applications.

Synthetic method of alicyclic diester

The invention discloses a synthetic method of alicyclic diester. The synthetic method comprises the following steps: enabling diacid comprising a multi-carbon lipid chain end group or diester containing a multi-carbon lipid chain end group to react with a first halogenation reagent, after the reaction is completed, adding a second halogenation reagent into a reaction product, after the reaction iscompleted, re-esterifying, and obtaining the di-ester of di-halogenation; adding the di-ester of the di-halogenation into an organic solvent, adding alkali to perform the reaction, after the reactionis completed, adding acid to perform the neutralization, and obtaining annular di-ester; and performing the reduction reaction for the annular di-ester, and obtaining the alicyclic diester. By adopting the synthetic method, a novel reaction path is developed, and the direct-chain end-group diacid or diester is used as a raw material to prepare the alicyclic diester by virtue of bromination reaction, ring-closing reaction and the reduction reaction. The initial raw material is low in cost, the process is simple, the reaction condition requirement is low, the safety is good, the product yield and purity are high, and the mass production is easy to realize. Moreover, the diester of a three-membered ring to an eighteen-membered ring can be prepared by utilizing the synthetic method of the invention.
