Description

A method for preparing 1,3-prop-1-enesultone,

The present invention relates to a process for the production of 1,3-prop-1-enesultone, which is easy and economical to manufacture and which can be mass-produced industrially.

1,3-Propene-1-enesultone (PRS) represented by the following formula (1) is a known compound widely used as an intermediate for pharmaceuticals, an additive for an electrolyte of a lithium ion secondary battery, and the like.

[Chemical Formula 1]

Figure 112015119387010-pat00001

As a method for preparing 1,3-propene-1-enesultone, Chem. Commun. 1997, 611 and Tetrahedron, 1999, 2245 (WH Lee et al.) Synthesized 2-bromo-1,3-propane sultone from allyl bromide via sulfonation, bromination and cyclization, And then, 1,3-prop-1-enesultone is produced through elimination reaction.

Figure 112015119387010-pat00002

According to the above method, 2,3-dibromo-1-propanesulfonate is synthesized to synthesize 1,3-prop-1-ene, and the resultant is cyclized to obtain 2-bromo- Should be synthesized. At this time, in the step of synthesizing and cyclizing 2,3-dibromo-1-propanesulfonate, a reduced pressure of 2 mmHg or less and a temperature of 130 ° C or more are required. In the reaction conditions, 2,3-dibromo- Sulfonate and 2-bromo-1,3-propane sultone are decomposed together, degradation of the yield is intensified. Particularly, as the amount of the reactant increases, the heating condition for a long time is deepened and an oligomer and a polymer substance connected in the form of sulfone ester can be produced together. From this, the desired product, 2-bromo-1,3- The separation becomes more difficult and the overall yield is lowered. Therefore, there is a problem that it is difficult to use the method for mass production.

In Synlett 1998 and 1411, 1,3-dibromo-5,5-dimethylhydantoin was reacted with allylsulfonyl chloride, which was obtained by reacting sodium allylsulfonate with phosphorus oxychloride to give 2-bromo-1,3 -Propane sultone, and then synthesizing the 1,3-prop-1-enesultone by a tribromohydrogenation reaction. However, the synthesis method has a problem that a high amount of 1,3-dibromo-5,5-dimethylhydantoin must be used in a considerable amount, and the yield is low.

Also, Synlett, 2002, 2019 (Peter Metz et al.) Has proposed a ring closing metathesis synthesis from vinyl intermediates, but it is difficult to use industrially because synthesis of vinyl intermediates is not very easy.

In SYNTHESIS No. 10, pp. 1696-1712 (2004), vinyl sulfonyl chloride is reacted with allyl alcohol to form an unsaturated sulfonate, which is then cyclized with a Grubbs ruthenium catalyst to obtain 1,3-prop- A method for producing a sultone is disclosed. However, the above method is difficult to produce vinyl sulfonyl chloride as an intermediate material, and since the price of Grubbs ruthenium catalyst is high, there is a problem in mass production.

Korean Patent Publication No. 2007-0101716 also discloses a process for preparing a halogen-substituted 1,3-propanesultone by a halogenation reaction of 1,3-propanesultone to prepare a halogen-substituted 1,3- And a second step of carrying out halogen hydrogen elimination reaction to the 1,3-propane sultone.

Figure 112015119387010-pat00003

However, in the above method, 3-halogeno-1,3-propanesultone, which is different in halogen substitution position, is produced as a by-product during the halogenation reaction of 1,3-propanesultone, and 3-halogeno-1,3-propane The sultone does not undergo a dehydrohalogenation hydrogenation reaction, and the target 1,3-propanesultone is not produced, so that the yield is not improved.

Korean Patent Laid-Open Publication No. 2009-0045027 discloses a method for producing 1,3-prop-1-enesultone through a chlorination reaction, a cyclization reaction and an elimination reaction as shown in the following reaction formula.

Figure 112015119387010-pat00004

However, the above method is not suitable for commercial production because the reagents used for bromodan, NBS, NCS and the like are expensive.

Accordingly, there is a need for a process for producing 1,3-prop-1-enesultone that is easy to manufacture and is suitable for mass production while eliminating the above problems.

Korean Patent Publication No. 2007-0101716 Korean Patent Publication No. 2009-0045027
