γ‐butyrolactam, δ‐valerolactam, ε‐caprolactam, and 1‐isoindolinone (phthalimidine) with up to three methyl moieties were synthesized according to the chemical formula MexSiLac(4–x) (x = 0, 1, 2, and 3). Using the lactams as starting materials four synthetic routes were tested: salt elimination, transsilylation, transamination, and metallation of the lactames followed by reaction with methylchlorosilanes.

γ-丁内酰胺,δ-戊内酰胺,ε-己内酰胺和1-异吲哚满酮(邻苯二甲酰亚胺)的内酰胺甲基硅烷根据化学式Me x SiLac (4– x)(x = 0,1,2和3)。使用内酰胺作为起始原料,测试了四种合成途径:内酰胺的除盐,硅烷化,氨基转移和金属化,然后与甲基氯硅烷反应。所有产品均通过NMR(1 H,13 C和29Si)和RAMAN光谱。选定的固体产物进行结晶,并通过单晶X射线衍射确定分子结构。研究了内酰胺甲基硅烷对苯基异氰酸酯和CO 2的反应性。
