Lithium, tert-butylamide

A characteristic reaction of sulfmylimines RNSO is the quantitative addition of R Li reagents to form adducts of the type Li[RNS(R )NR]. ° The structures of these sulfmimidinates are discussed in Section 10.4.4." The reactions of RNSO derivatives with two equivalents of lithium tert-butylamide result in the formation of diazasulfite anions [OSNR(N Bu)] (9.12) (Eq. 9.12)." The dilithium derivatives of these dianions form hexameric thirty-six atom (Lii2Ni206S6) clusters with structures that are dependent on the nature of the R group. 

The corresponding tellurium diimide BuNTe( -N Bu)2TeN Bu (10.7) may be obtained in good yields from the reaction of lithium tert-butylamide with TeCU in THE (Eq. 10.3). °" In toluene solution this reaction also produces the cyclic tellurium(II) imide (TcN Bu)3. The dimer 10.7 is obtained as an orange solid, which can be purified by vacuum sublimation at ca. 90°C.

The carbonylation of alkali metal amides was described in 196785 the reaction of lithium tert-butylamide (80) with CO at 50 °C was reported in 1971 to give apparently an orange solution of ferf-butylcarbamoyllithium (81), which was trapped with trimethylelement chlorides derived from silicon, germanium and tin86. When this reaction was performed at — 75 °C it was found that carbamoyllithium equilibrated to the...
