“…The best yield of about 60% of the six-membered ring was observed after a reaction time of 4 h at room temperature. 175 A proposed reaction mechanism is described in section V.l. The reaction takes place also with sodium metal204 (Scheme 25).…”

“…[6] They are used for the synthesis of compounds with elements in low coordination states as well as for the synthesis of new main-group compounds and clusters. [8] Although functional silyl anions (SiCl 3 À , [9] Si(OR) n Me 3Àn À ) [10] are known, they have been postulated as reactive intermediates generated in situ in the presence of quenching agents.

“…[6,7] Silyl anions were long limited to triorganosilyl anions. [8] Although functional silyl anions (SiCl 3 À , [9] Si(OR) n Me 3Àn À ) [10] are known, they have been postulated as reactive intermediates generated in situ in the presence of quenching agents. [8] Mixed alkyl amino silyl anions (Li[Si(NEt 2 )Ph 2 ], Li[Si-(NEt 2 ) 2 Ph],L i[Si(NEt 2 )PhMe]) represent the first examples of stable functionalized silyl anions.…”

“…[6,7] Silylanionen waren lange auf Tr iorganosilylanionen beschränkt.
