2)3−クロロ−2−ブテニル−1H−イミダゾール−1−カルボジチオエート
式(I)の化合物を製造するための本発明による方法の一実施態様は、強く臭う副生物の形成をまねきかつ別の精製段階を必要不可欠にする副反応を回避するために、反応が、後処理段階又は精製段階なしで、同じ有機相、好ましくはエーテル、より好ましくはテトラヒドロフラン中で、−78℃〜80℃、好ましくは0〜30℃の温度で実施されることにより特徴付けられる。得られる生成物は、生じたアルカリ金属ハロゲン化物(例えば水酸化カリウム)の濾別後に、溶液の蒸発により純粋に得られる。
方程式1:
平均分子量=(モノマーのモル量・モノマーの分子量・変換率)/(調節剤のモル量)
ジチオカルバミン酸エステルの本発明による製造方法:
本発明による方法によるジチオカルバミン酸エステルを製造するために、THF 500ml(無水)及び1molの金属カリウム(変法A)又は液体NaK合金(変法B)又は水素化カリウム(変法C)を、撹拌機、温度計及び滴下漏斗を備えた1L四つ口フラスコ中に、窒素雰囲気下に室温で装入した。これに、アミン化合物1mol(THF 150ml中に溶解させた)を、0.5hかけて添加した。アルカリ金属をアミンで塩に完全に変換した(視覚制御)後、二硫化炭素1mol(THF 240ml中に溶解させた)を添加し、かつ混合物を1h撹拌した。生じたジチオカルバメート塩を、カルバミン酸塩を前もって単離せずに、有機ハロゲン化物化合物1.5molと反応させて所望のジチオカルバミン酸エステルを得た。反応を、ジチオカルバミン酸塩の完全な変換まで、GC−制御(GC=ガスクロマトグラフィー)下に行った。生じたアルカリ金属ハロゲン化物を分離するために、溶剤を真空中で除去し、かつ残留物をペンタン500mLでスラリー化した。アルカリ金属ハロゲン化物を濾別し、ついで溶液を50℃で0.1barの真空中での濃縮した後に生成物を、十分な純度で得た。変換されていない有機ハロゲン化物を、その際、取得し直した。
クロロプレンの乳化重合のためにここで例で使用される方法:
3 lガラス反応器中に、次のものを水相として装入した(全ての部は質量部である):脱イオン水125部(1,250g);70%溶液としてのDresinate 731 2.80部(40g);30%溶液として縮合ナフタレンスルホン酸0.3部(10g)、NaOH 0.65部(6.5g)。この混合物に、クロロプレン100部(1000g)及び所望の量X部の調節剤からなるモノマー相を添加した(第1表参照)。重合を開始する前に、反応器を、1.5h、窒素ですすいだ。反応を、窒素雰囲気下に行った。60%変換率を達成するまでの重合時間は、1〜5hであった。
略符号:
Dresinate 731 = 不均化された樹脂酸のNa塩(例えばAbieta社から商業的に入手可能である)(樹脂酸は木のやにに匹敵しうる天然産物である)
第1表は、変法Aによる多様な調節剤を用いたクロロプレンの乳化重合の結果を与える:1及び2欄は、調節剤化合物の置換基Z及びRを示す。3欄は、利用された方法を与える。第4欄は、式(I)のプロトン化された置換基ZのpKa値を与える。5及び6欄は、使用された調節剤の名前及び構造式が挙げられる。7欄は、調節剤化合物の番号が列挙されている。8欄は、8.6%トルエン性溶液からの溶液粘度として測定された60%で得られたポリマーの溶液粘度を示す。9欄は、モノマー相中で、混合物に添加した調節剤の量[mmol]を挙げている。10欄は、GPC測定による達成された数平均分子量を挙げている。11欄は、本発明による例(数字)及び比較例(文字)を区別する。
M:ベンジル 1−ピロールカルボジチオエートの合成:
撹拌しながら、ジメチルスルホキシド(20mL)中の水素化ナトリウム(0.48g、20mmol)の懸濁液にピロール(1.34g、20mmol)を滴加した。添加が完了してから、生じている褐色の懸濁液をさらに30min、室温で撹拌してから、二硫化炭素(1.52g、20mmol)を添加した。溶液を、さらに30min、室温で撹拌し、かつ最終的に塩化ベンジル(2.53g、20mmol)を添加した。1h後、水(20mL)、引き続いてジエチルエーテル(20mL)を、反応混合物に添加した。有機相の分離後、水相をジエチルエーテル各20mLで2回抽出した。一つにまとめた有機相を、硫酸マグネシウムを用いて乾燥させ、濾過し、かつ溶剤を留去した。粗生成物を、生成物の単離のために、石油エーテル中の5%酢酸エチルを用いてクロマトグラフィーにより分離した。純生成物を、黄色の油状物として50%の収率(2.34g)で単離した。
N:ベンジル 1−イミダゾールカルボジチオエートの合成:
ジクロロメタン(10mL)中のチオカルボニルジイミダゾール(0.89g、5.5mmol)の溶液に、撹拌しながら、ベンジルメルカプタン(0.68g、5mmol)を室温で滴加した。溶液を、同じ温度で3min撹拌し、かつ最終的に溶剤を真空中で除去した。残留物を、クロマトグラフィーにより(シリカゲル60、70〜230メッシュ) 溶離剤として比3:7で酢酸エチル及び石油エーテルからなる溶剤混合物を用いて分離した。それにより、生成物ベンジル 1−イミダゾールカルボジチオエート(65)が、淡黄色の固体として54%の収率 (0.78g)で単離することができた。
