3403 C, 65.7; H,9.4; N, 8.7. When the same reaction was run keeping the temperature of the stirred mixture at 35-40" for 40 hr and 50" for 5 hr, 95% of the silane was consumed and the yields were: 35% of XI, 40z of XIV, 20 of XIII, and 5 % of XII, based on Cpicoline reacted. Silylation of 2-Picoline. When trimethylsilane was passed into a stirred suspension of Pd catalyst (10% on carbon) in dry 2-picoline in the same manner used for the other picolines, no reaction was observed. A faint trace (
