 Title    Von 1,5-funktionelIen Trisiloxanen zu (SiO)4-, [Si(OSiN)2Si]-und [0 (S i0 S i)2N]-Ringen From 1,5-Functional Trisiloxanes to (SiO)4-, [Si(OSiN)2Si]-, and [0(Si0Si)2N]-Rings  
 Abstract    C om pounds of the general formula (CM e3)2Si(R)O H , (R = Cl, O H . N H :) react with «-C 4H,,Li or Na to give the alkali silanolates 1—5 .1 —5 serve as starting materials in the reactionsw ithchlorosilanes for the synthesis o f siloxanes (6—12). Ring closure reactions of dilithiated 9 ,1 1 , and 12 occur with SiCl4 (13) and C l,SiM e, (15, 16). 13 contains an (SiO)4. 15 an Si(O SiN),Si. and 16 an 0 (S i0 S i) ,N eight-m em bered ring. Hydrolysis o f 13 leads to the formation o f the hydroxy-substituted eight-m em bered ring 14. The crystal structures of (C M e3),S i(O H) —O —SiM e, —Ö —(H ,N)S i(C M e3), (11) and M e,Si[O Si(C M e3),N H ],S iM e, (15) are reported and discussed.
