有机合成中大量的反应涉及到对某个基团的保护或者对某个被保护的基团经行去保护的工作。不能做好官能团的保护和去保护，可以肯定完成不了或完成不好有机合成工作。不少保护和去保护工作是为实现合成目标必须经行的，但也有许多保护和去保护工作的经行是一种无奈，反映出了我们对化学反应的把握是随心所欲还是差的很远。
这是一种挑战，推动我们朝着最终能完全了解，并控制各种分子中原子间的成断键过程前进。
尤其在天然产物的合成当中，保护和去保护工作十分重要，甚至可以说非常关键。多种保护基产品的出现，给研究人员达到合成目标，提供了一种非常重要的有机合成手段。

Reactions of alcohols with silyl chlorides in the presence of N-methylimidazole were significantly accelerated by addition of iodine. A general and high yielding method for efficient silylation of primary, secondary, and tertiary alcohols was developed.
