Trichlorosilane reaction
WebDuring this reaction step an Si-X group will react with water to form an Si OH (silanol) group with release of an HX molecule. The overall reaction rate of SAM formation is determined by this step and depends on the nature of the leaving group X. The hydrolysis rate decreases along the sequence: X = Cl, X = OCH 3, X = O C 2 H 5. 3.
