 Title    Studies on l-Trimethylsilyl-2,4,6-triethylborazine and Related Species  
 Abstract    The unsymmetrically substituted borazine (C6H 5)3B3N 3H2[Si(CH3)3] has been obtained from the reaction o f C6H 5BC12 with HN [Si(C H 3)3]-,, and an improved synthesis o f (C2H 5)3B3N 3H 2[Si(CH3)3] has been developed. The reaction o f the latter with an excess o f BC13 proceeds with the ultimate formation o f Cl3B3N 3H 2[Si(CH3)3], whereas the reaction with one molar equivalent o f BBr3 leads to the formation o f Br(C2H5)2B3N 3H-,[Si(CH3)3], but which is contaminated by substantial am ounts o f Br(C2H 5)2B3N 3H3 besides a diborazinyl and additional products. C6H 5BBr2 reacts with N [Si(C H 3)3]3 to give the aminoborane [(CH3)3Si]2N BBr(C6H 5), but C6H5BC12 does not undergo a reaction under analogous condi­ tions.
