Description
5.00gのトリクロロシランを、0.17gのトリフルオロメタンスルホン酸亜鉛および10.75gのアセトニトリルと混合し、トリフルオロメタンスルホン酸亜鉛のほとんどを溶解させた。1.49gのヘキサメチルジシラザンを2分にわたって添加した。溶液を次に還流(38.5℃)に加熱し、トリクロロシランが消費されるにつれて温度をゆっくり上げた。加熱を52分間続行し、そこでそれは51.3℃に達した。温度を2分間保持し、次に6分間ゆっくり放冷した。熱源を取り除いた。粗物質のGCは、TCDZの70%収率を示した。
粗生成物1,1,3,3−テトラクロロジシラザンを、15cmのビグリュー(Vigreux)カラムによって蒸留して96%の1,1,3,3−テトラクロロジシラザンを得た。
0.25gのトリフルオロメタンスルホン酸亜鉛を5.00gのアセトニトリルに溶解させた、これは、完全に溶解するのにしばらく時間がかかる可能性がある。混合物を次に、11.75gの四塩化ケイ素に添加し、加熱してこの溶液を還流させた。還流する溶液に、調製1の、5.00gの1,1,1−トリクロロ−3,3,3−トリメチルジシラザンを5分にわたって添加した。反応物を約5時間還流させた。粗生成物のGC−TCDは、混合物が47.5%の収率を与えることを示した。
実施例3からの混合物を、15cmのビグリュー(Vigreux)カラムによって蒸留して1.24gの95%のヘキサクロロジシラザンを集めた(19.4%単離収率)。
アセトニトリルに溶解させた3%のトリフルオロメタンスルホン酸亜鉛を、四塩化ケイ素入りの圧力反応器へロードして3%の全質量の反応混合物を得た。反応器を140℃に加熱し、ヘキサメチルジシラザンを5時間にわたって供給し、室温まで冷却して粗混合物中の2.8%収率の1,1,1,3,3,3−ヘキサクロロジシラザンを得た。
