Reaction Steps

N-trimethylsilyl-2-chloro-2-methyl-1-aza-2-silacyclopentane (cyclic APMCS, which may be referred to as c-APMCS) was prepared as follows. To a 300 mL nitrogen purged bottle equipped with stir bar was added 20.1 g (0.1 mol) of N,N-bis(trimethylsilyl) allyl amine, 11.5 g (0.1 mol) of dichloromethylsilane, and 0.81 mL of 2.4 wt % Karsted's Catalyst in xylene. The solution was stirred for 72 hrs, then heated at 65° C. for 2 hrs, and heated at 100° C. for a further 3 days. The product was distilled at 85-90° C. at 25 mm Hg. GC/MS confirmed structure. Proton NMR was also used to determine structure.
