[求助] 求大虾 论文翻译

The formation of carbon-carbon bonds is perhaps one of
the most important reactions in organic chemistry. Currently,
the most developed methods for forming sp2
carbon -carbon bonds involve transition-metal-catalyzed cross-coupling
reactions between Ar -M(M) SnR 3, B(OR)2, MgX) and Ar-X(X=halogen, sulfonate).
Quite often, these func-tionalized starting materials are either expensive or have to
be prepared in several steps. Regioselective conversion of
C-H to C-C bonds would result in shortening of synthetic
schemes by allowing the use of readily available starting
materials.

碳 - 碳键的形成可能是有机化学中一个最重要的反应。目前,形成SP2碳 - 碳键的最先进的方法涉及过渡金属催化的Ar -M(M) SnR 3, B(OR)2, MgX) .和Ar- (X =卤素,磺酸)之间的交叉偶联反应。很多时候,这些功能化的起始原料,要么是昂贵的,要么有好几个前处理步骤。若可以使用现成易得起始原料,C-H键和C-C键之间的选择性转换可能可以缩短合成计划。
给你参考下。
如若这般,当初又为了什么?

碳-碳键的形成可能是有机化学里面最重要的反应之一。目前,关于形成sp2碳-碳键的最新方法是经过渡金属催化,于Ar -M(M) SnR 3, B(OR)2, MgX) and Ar-X(X=halogen, sulfonate)之间发生交联反应而形成。这些功能化的起始物质通常价格昂贵抑或是前处理过程冗杂。所以选用快速易得的起始物质能完成从碳-氢键到碳-碳键的转化,从而使反应的路线得到缩减。

第一句的perhaps翻成可以说是也行吧
