[求助] 被编辑拒稿说翻译不地道(化学方面,实验部分,现在已经差不多翻完了,谢谢)

Ⅰ  Equipped with a magnetic stirrer in 50 ml flask, Join compounds (1a~b or 1c~d) and using dried DMF dissolved. This mixture cooled to 0℃,then adding 1.1 mol NaH,After the hydrogen volatiled ,stirred at room temperature for 1 h.
Ⅱ  Added 1.2-2 mol B to the above mixture,room temperature for 18-29 hours stirring (monitored by TLC).Add water to stop the reaction,third extraction with ethyl acetate ; organic layer dried with MgSO4 ,purified by column chromatography,ether recrystallization.
Ⅰ  在装有磁力搅拌器的50ml烧瓶中,加入化合物(1a~b或1c~d)并用干燥的DMF溶解,此混合液冷却至0℃后,小心加入两倍物质的量的NaH,待氢气挥发完毕后,在室温条件下搅拌1h。
Ⅱ  再往上述混合液中加入等物质的量的B,室温条件下搅拌22小时(TLC跟踪)。加水使反应停止,用乙酸乙酯萃取三次;有机层用无水MgSO4干燥,溶液旋蒸后柱层析,乙醚重结晶。
Under N2,the reaction was carried out three-neck round-bottom flash (250mL) equipped with  thermometer 、condenser tube ,then join compounds(2a~b or 2c~d) dissolving dried 20mL of CH3CN ,2mol Et3N、10mol% Pd(OAc)2,30mol%PPh3, the stirring was continued for 6 hours (monitored by TLC )at 85±0.5 ℃.The mixture was filter and concentrated ,the product was purified by column chromatography.
在装有磁力搅拌器、回流冷凝管和温度计的50ml的三颈烧瓶中,加入化合物(2a~b或2c~d)和两倍物质的量的Et3N、10mol%的Pd(OAc)2,30mol%pph3,并用干燥的甲苯溶解,混合液在氮气氛中、85℃条件下加热回流搅拌6h。反应毕,将混合液经过滤、溶剂旋蒸后得到粗产物,再经过柱层析提纯得到目标化合物(3ab或3c~d)。

  South African Journal of Chemistry http://journals.sabinet.co.za/sajchem/chem_aut.html要投的期刊~谢谢。

谢谢金币,不过我认为,join一般在化工翻译中不作为加入的最好翻译

Compounds (1a~b or 1c~d) were dissoved by DMF in a 50ml flask with magnetic strrer. When cooled it to 0℃,add 1.1 mol NaH,and the reaction were carried out for 1h after the hydrogen volatiled.

Ⅰ  Join compounds (1a~b or 1c~d) to 50 ml flask equipped with magnetic stirrer and using dried DMF for dissolving. After the mixture cooled to 0℃,adding 1.1 mol NaH, when the hydrogen volatiled ,stirred for 1 h at room temperature.

Ⅱ  Added 1.2-2 mol B to the above mixture, stirring at room temperature for 18-29 hours (monitored by TLC).Add water to stop the reaction, extracting three times with ethyl acetate ; dry the organic layer  with dried MgSO4 ,then purified by column chromatography,and ether recrystallization.


Under N2,the reaction was carried out in three-neck round-bottom flash (250mL) equipped with  thermometer and condenser tube , join compounds(2a~b or 2c~d) dissolving dried 20mL of CH3CN ,2mol Et3N、10mol% Pd(OAc)2,30mol%PPh3, the stirring was continued for 6 hours (monitored by TLC )at 85±0.5 ℃.The mixture was filtered and concentrated ,then the product was purified by column chromatography.

困那...术语我没有查了,感觉前面两段怎么像是机器翻译的?

我的译本:

Ⅰ Put compounds (1a~b or 1c~d)  into 50 ml flask equipped with a magnetic stirrer, and  dissolved with dry DMF. after cooling the mixture to 0℃, added twice mols of NaH,After the hydrogen volatilization,stirred at room temperature for 1 h.
Ⅰ  在装有磁力搅拌器的50ml烧瓶中,加入化合物(1a~b或1c~d)并用干燥的DMF溶解,此混合液冷却至0℃后,小心加入两倍物质的量的NaH,待氢气挥发完毕后,在室温条件下搅拌1h。

Ⅱ  Added same mol of B to the above mixture,stirred under room temperature for 18-29 hours  (monitored by TLC).Added water to stop the reaction, extracted with ethyl acetate for three times; dried the organic layer with Anhydrous Magnesium, after concentration, purified by column chromatography,and recrystallized with ether
Ⅱ  再往上述混合液中加入等物质的量的B,室温条件下搅拌22小时(TLC跟踪)。加水使反应停止,用乙酸乙酯萃取三次;有机层用无水MgSO4干燥,溶液旋蒸后柱层析,乙醚重结晶。
Under N2,the reaction was carried out in three-neck round-bottom flask (250mL) equipped with  thermometer 、condenser tube ,then added compounds(2a~b or 2c~d) ,dissolving with dry 20mL of CH3CN ,2mol Et3N、10mol% Pd(OAc)2,30mol%PPh3, the stirring was continued for 6 hours (monitored by TLC )at 85±0.5 ℃.The mixture was filtered and concentrated ,the product was purified by column chromatography.
在装有磁力搅拌器、回流冷凝管和温度计的50ml的三颈烧瓶中,加入化合物(2a~b或2c~d)和两倍物质的量的Et3N、10mol%的Pd(OAc)2,30mol%pph3,并用干燥的甲苯溶解,混合液在氮气氛中、85℃条件下加热回流搅拌6h。反应毕,将混合液经过滤、溶剂旋蒸后得到粗产物,再经过柱层析提纯得到目标化合物(3ab或3c~d)。
