Abstract
Reactions of indium amide complexes with fluorinated alcohols give indium f luoroalkoxide complexes. In[N-t-Bu(SiMe3)](3) reacts with 3 equiv of (CF3)M e2COH to give the homoleptic alkoxide dimer [In{mu-OCMe2(CF3)}-{OCMe2(CF3)} (2)](2), but reactions involving the more acidic alcohols (CF3)(2)MeCOH and (CF3)(2)CHOH yield products containing t-BuNH2, which is derived from the amide ligands. Thus, In[N-t-Bu(SiMe3)](3) reacts with (CF3)(2) MeCOH to giv e In[OCMe(CF3)(2)](3)(H2N-t-Bu) and with (CF3)(2)CHOH to yield In[OCH(CF3)( 2)](3)(H2N-t-Bu)(3) and [H3N-t-Bu] [In(OCH(CF3)(2))(4)(H2N-t-Bu)]. Reaction s of (CF3)(2)MeCOH and (CF3)(2)CHOH with In(tmp)(3) (tmp = the anion derive d from 2,2,6,6-tetramethylpiperidine) and In(NEt2)(3) are less complicated. In(tmp)(3) reacts with 3 equiv of (CF3)(2)CHOH to give In[OCH(CF3)(2)](3)( Htmp) and with 4 equiv of (CF3)(2)CHOH or (CF3)(2)MeCOH to yield the salt c ompounds [H(2)tmp][In{OCR(CF3)(2)}(4)] (R = H, Me). Trigofial bipyramidal [ H2NEt2][In(OCH(CF3)(2))(4)(HNEt2)] and octahedral mer-In[OCMe(CF3)(2)](3)(p y)(3) are isolated from reactions involving In(NEt2)(3). Crystal structure determinations of [In{mu-OCMe2(CF3)}{OCMe2(CF3)(2)}(4)], In[OCMe(CF3)(2)}(4 )(H2N-t-Bu] [In(OCH(CF3)(2)}(4)(H2N-t-Bu)]. EtOEt, In[OCH(CF3)(2)](3)(Htmp) , [H(2)tmp] [In{OCMe(CF3)(2)}(4)], In[OCMe(CF3)(2)](3)(py)(3), and [H2NEt2] [In{OCH(CF3)(2)}(4)(HNEt2)] were carried out.
