Abstract
Description
収率%=(実際の収率)/(理論的収率)×100
周知であるように、実際の収率および理論的収率は、重量パーセントまたはモルパーセントに基づき得る。実際の収率は、無次元数である。
例示的な実施形態によれば、ルイス酸触媒は、一般式M(R1)1(R2)1(R3)1(R4)0または1を有し、式中、Mは、ホウ素、アルミニウム、インジウム、ビスマス、またはエルビウムであり、R1は、第1のフルオロアルキル置換フェニル基を含み、R2は、第2のフルオロアルキル置換フェニル基または第1のフルオロ置換フェニル基もしくはクロロ置換フェニル基(すなわち、第1のフルオロ/クロロ置換フェニル基)を含み、R3は、第3のフルオロアルキル置換フェニル基または第2のフルオロ置換フェニル基もしくはクロロ置換フェニル基(すなわち、第2のフルオロ/クロロ置換フェニル基)を含み、任意のR4は、官能基または官能性ポリマー基である。一般式中、Mは、金属塩イオンとして存在しても、この式に一体的に結合した部分として存在してもよい。R1、R2、R3、およびR4は各々、互いに独立しており、例えば、R1のフルオロアルキル置換フェニル基は、R2のフルオロアルキル置換フェニル基と同じであっても、異なっていてもよい。しかし、R1、R2、およびR3の各々が、全て同じ(例えば、同じフルオロアルキル置換フェニル基)ではないように、R1は、R2およびR3のうちの少なくとも1つとは異なっているが、R1は、R2またはR3と同じであっても、同じではなくてもよい。
触媒成分は、任意で、DMC触媒を含んでもよい。例示的なDMC触媒およびDMC触媒を生成する方法は、例えば、米国特許第3,278,457号、同第3,278,458号、同第3,278,459号、同第3,404,109号、同第3,427,256号、同第3,427,334号、同第3,427,335号、および同第5,470,813号に記載されている。例示的な種類のDMC触媒は、亜鉛ヘキサシアノコバルテート触媒錯体である。mDMC触媒錯体は、DMC触媒を形成する方法を修正したものを使用して調製することができる。DMC触媒、例えば、当該技術分野で既知のものが、ルイス酸触媒を含む触媒系で使用されてもよい。DMC触媒は、提供される第1または第2の触媒であってもよい。
Mb[M1(CN)r(X)t]c[M2(X)6]d・nM3 xAy (式1)
式中、MおよびM3は各々、金属であり、M1は、Mとは異なる遷移金属である。X1は、M1イオンと配位するシアン化物以外の基を表す。M2は、遷移金属である。X2は、M2イオンと配位するシアン化物以外の基を表す。X1またはX2は各々独立して、ハロゲン、硫酸塩、硝酸塩、リン酸塩、炭酸塩、または塩素酸塩であり得る。例示的な実施形態では、X1およびX2は、同じものであり、かつ塩化物である。A1は、アニオンを表し、b、c、およびdは、静電的に中性の錯体を反映する数であり、rは、4〜6であり、tは、0〜2であり、xおよびyは、金属塩M3 xAyの電荷のバランスをとる整数であり、nは、ゼロまたは正の整数である。例えば、nは、0.01〜20である。前述の式は、多くの場合にDMC触媒錯体内に存在するt−ブタノールなどの中性錯化剤の存在は反映していない。

触媒成分の使用
触媒合成の一般的な生成は、以下のとおりである。特に明記されない限り、化学物質の全ての実験手順および操作は、窒素パージしたグローブボックス内またはシュレンクライン上で実行する。全てのバルク反応溶媒(トルエン、ジエチルエーテル、ヘキサン、テトラヒドロフラン(THF))は、アルミナおよびQ5反応性スカベンジャーのカラムを通過させることによって乾燥させる。他の全ての溶媒は、Aldrichから無水等級で購入し、使用前に活性化3Å分子ふるい上で保管する。Cambridge Isotope Laboratories,Inc.から得たNMR溶媒(CDCl3およびC6D6)は、分子ふるいで乾燥させるか、またはC6D6の場合、Na/K合金を使用して乾燥させる。さらに、1−ブロモ−2,3,4,5,6−ペンタフルオロベンゼン、1−ブロモ−3,5−ビス(トリフルオロメチル)ベンゼン、1−ブロモ−3,4,5−トリフルオロベンゼン、1−ブロモ−2,6−ジフルオロベンゼン、1−ブロモ−2−クロロ−4,6−ジフルオロベンゼン、1−ブロモ−2,4,6−トリフルオロベンゼン、1−ブロモ−2−フルオロ−3−トリフルオロメチルベンゼン、1−ブロモ−2−フルオロ−4−トリフルオロメチルベンゼン、1−ブロモ−2,5−ビス(トリフルオロメチル)ベンゼン、および1−ブロモ−2,4−ジフルオロ−3−トリフルオロメチルベンゼンは、Oakwood Chemicalから購入し、受け取ったままで使用する。1−ブロモ−2,3,5,6−テトラフルオロ−4−トリフルオロメチルベンゼンは、Alfa Aesarから購入し、受け取ったままで使用する。また、n−ブチルリチウム(ヘキサン中公称1.6または2.5Mの溶液)、トリイソプロピルボレート、三塩化ホウ素(トルエン中1.0Mの溶液)、クロロトリメチルシラン、ヘキサクロロベンゼン、および無水HCl(ジエチルエーテル中2.0Mの溶液)は、Sigma−Aldrichから得、受け取ったままで使用する。さらに、指示薬として1,10−フェナントロリンを有するトルエン中1.00Mのデカノールを使用して、n−ブチルリチウム(ヘキサン中1.6または2.5Mの溶液)を使用前に滴定する。ビス(3,5−ビス(トリフルオロメチル)フェニル)クロロボラン(Samigullin et al.,Organometallics,2014,33,3564−3569)は、文献の手順に従って調製する。
