Lactamomethylsilanes of γ‐butyrolactam, δ‐valerolactam, ε‐caprolactam, and 1‐isoindolinone (phthalimidine) with up to three methyl moieties were synthesized according to the chemical formula Me x SiLac (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. All products were analyzed by NMR ( 1 H, 13 C and 29 Si) and RAMAN spectroscopy. Selected solid products were crystallized and the molecular structure was determined by single‐crystal X‐ray diffraction. The reactivity of the lactamomethylsilanes towards phenylisocyanate and CO 2 was studied.
