- an embodiment used for a Mg compound-supported titanium catalyst used for olefin polymerization is known.
- olefin polymerization catalyst Ziegler reported in 1953 that ethylene polymerizes even at low pressure by combining titanium tetrachloride and organoaluminum compound, followed by Natta with titanium trichloride and organoaluminum compound containing halogen. It is one of the technologies that have made great progress to date with the discovery of the so-called Ziegler-Natta catalyst, which reported the first propylene polymerization in combination. Among them, it was found that a catalyst containing titanium tetrachloride, a magnesium compound and a Lewis base, which is called a third-generation catalyst, can achieve both high polymerization activity (high productivity) and high stereoregularity in the polymerization of propylene. .. This was an opportunity for propylene polymers (polypropylene) to spread around the world.
- the Lewis base (hereinafter also referred to as “internal donor”), which is one of the main components of the above-mentioned third-generation catalyst component (hereinafter, also referred to as “solid titanium catalyst component”), greatly affects the catalytic performance. It has been found that various Lewis bases have been developed so far.
- Examples of the Lewis base used in the Cheegler-Natta catalyst include ethylbenzoate, phthalic acid ester, 1,3-diketone (Patent Document 1), malonic acid ester (Patent Document 2), and succinic acid ester (Patent Document 3).

以下に、本発明のエステル化合物(A)の具体例を示すが、本発明のエステル化合物(A)はこれらに限定されるものではない。
本発明のエステル化合物(A)は、環が連結した構造を持ち、好ましくは架橋構造(上記XまたはYに該当する構造)を併せ持つ。この要件によって立体配座が制約され、環に結合した二つの隣接するエステル基の距離と向きが固定化される。その結果、塩化マグネシウムにエステルが配位した際にエステルの配位様式が制限され、チタン原子、塩化マグネシウム、エステル化合物からなる剛直な重合環境が形成されると推察している。そのような環境下で重合が進行すると、ポリマー鎖の向きとプロピレンの挿入方向が高度に制御され、高立体規則性重合に適した触媒が形成されると考えている。エステルが架橋構造を含む環に結合した骨格(例えば、式(5)、(6)および(9))はエステル部位の距離と向きが制約されるため、チーグラー触媒用内部ドナーとしてより優れた骨格である。また、エステル部位がシクロヘキサン骨格に直接結合した骨格(例えば式(8))であっても、シクロヘキサン骨格に架橋構造を含む環構造が縮環することでシクロヘキサン骨格の立体配座が制約され、結果的に同様の効果を有すると考えられる。以上述べたように、ここでは6員環構造を有する構造について説明したが、この推察に基づけば、式(1)で表される構造、より好ましくは式(2)~(4)で表される多環構造を有するエステル化合物であれば、具体的に例示した化合物以外であっても同様の効果を期待できるものであり、5員環から10員環構造であっても同様の効果が発現することは明らかである。
<エステル化合物(A)の製造方法>
本発明のエステル化合物(A)の製造方法は特に限定されず、例えば、対応するオレフィンをジオール化反応、ジエステル化反応を経て得ることができる。また、例えば、アントラセン類の様な特定の多環化合物を用いたカーボネート化反応、ジオール化反応、ジエステル化反応を経て得ることもできる。より具体的には、以下の様にして製造することができる。
下記式(21)に示すオレフィンは、例えばシクロペンタジエンとノルボルネンのディールスアルダー反応によって合成することができる(非特許文献1)。また、下記一般式(33)に示すオレフィンは、例えば、置換インデンと置換ジエンのディールスアルダー反応によって合成することができる(特許文献11)。ジエンは前駆体であるジエンの二量体(例えばジシクロペンタジエン)を原料にして用いることもできる。また、ディールスアルダー反応によって得られる生成物は、しばしばendo体とexo体の混合物となる(下記式(22)および(34)参照)が、本発明にはどちらの異性体であっても適用することができる。すなわち、混合物であっても、endo体のみであっても、exo体のみであってもよい。これらのendo体構造、exo体構造は、目的物であるエステル化合物にまで反映される場合が多い。
≪アントラセン類の合成≫
また、前記R1~R24が結合して環を形成する部位が、更に二重結合や環構造、特に二重結合を含む環構造を有する構造である化合物は、例えば、アントラセン類を炭酸ビニレンとのディールスアルダー反応でカーボネート化合物とした後、ジオール化反応、ジエステル化反応を経て、合成することができる。
≪ジオールの合成≫
エステルの前駆体であるジオール体(式(23)および式(35))は、対応するオレフィン(式(21)および式(33))を原料にして製造することができる。例えば、オレフィンと過マンガン酸カリウム(非特許文献4)または四酸化オスミウム(非特許文献5)との反応により直接ジオール体(式(23)および式(35))を得ることができる。
ジオール体(式(23))の前駆体である環状カーボネート(式(24))は、対応するジエンと炭酸ビニレンのディールスアルダー反応によって製造することができる(非特許文献19)。上記と同様にジエンは前駆体であるジエンの二量体を原料にして用いることもできる。また、ディールスアルダー反応によって得られる生成物は、しばしばendo体とexo体の混合物となるが、本ディールスアルダー性体であっても適用することができる。この反応は、ジエンの代わりにアントラセンなどの多環芳香族化合物を用いて、後述する実施例に示したような特定構造の多環式カーボネートを得ることもできる。
上記式(1)に対応するエステル体は、ジオール体(式(23))と酸クロライドを塩基存在下反応させることで合成することができる(式25)。塩基としては特に限定されないが、例えば水酸化ナトリウム、水酸化カリウム、アミン塩基を用いることができる。また、ジオール体とカルボン酸を酸触媒存在下反応させることで合成する方法や、DCC(非特許文献11)などの縮合剤を使用して合成することもできる(式(26))。ジオール体(式(3’))に1等量の酸クロライドまたはカルボン酸を反応させた場合、式(24)に相当する異性体が生成し得るが、続いて酸クロライドまたはカルボン酸を反応させれば式(1)に相当する化合物を得ることができる。この時、L1とL2は同一であっても異なっていてもよい。また、ジオール体を、アゾカルボン酸エステルおよびトリフェニルホスフィンの存在下、カルボン酸と反応させることで合成することもできる(非特許文献12)。
本発明のエステル化合物(A)は、前記した通り、固体状チタン触媒成分のルイス塩基成分として好適であるが、この用途に制限されるものではない。各種樹脂への添加剤、化粧料や皮膚外用剤、殺菌組成物、酸化防止剤、キレート剤等、公知の添加剤用途に適用できる可能性が有るのは言うまでもない。
