 Title    Phosphazenylcyclophosphazene Syntheses U sing Silylmonophosphazenes * > *  
 Abstract    The reactions of the lialogenocy clotri -phosphazatrienes N 3 P 3 F 6 and N 3 P 3 CI6 with the reagentsMesSiR [R = NP(NMe2)3 ,NPMe3 , NPMe2 Ph, NPMePh2, N P Ph3, and N P (O Et)3] are discussed, and conclusions are drawn about some of the factors controlling the course and rate of these reactions. Some novel phosphazenyl-derivatives, N 3 P3 X 5 R [X = F or Cl, R = NP(NMe2)3; X = F, R = N P (O Et)3] are reported.

 Title    S 0 2-Einschiebung in Triphenylvinylzinn D eterm ination of the Nucleophilicity of Tin-Carbon Bond, I I 1 S 0 2-Insertion into Triphenylvinyltin  
 Abstract    The S 0 2-insertion into tin-carbon bonds of mixed tetraorganostannanes, R 3SnR / (R = C6H 5, CH3; R' = CH3, C6H 5, CH2 = CH), is determined by the nucleophilicity of the organic residue attached to metal and shows a decreasing rate in the order aryl > alkenyl > alkyl. A correlation to Taft's constant is given. The behaviour of triphenylvinyltin toward sulfur dioxide is in good agreement with this S 0 2 takes place only into Sn-C6H 5 bond.
