“…Raston et al4 have investigated the reaction of the trimethylamine adduct of alane Me 3 N·AlH 3 with chalcogen or organochalcogenides. Power et al5 have reported one example of the reaction of an aluminum dihydride with an organochalcogenide and our group has discussed the reaction of a series of aluminum dihydrides with chalcogen,3,6 where the isolation and structural characterization of some novel compounds {such as LAl(SeH) 2 , LAl(SeH)Se(SeH)AlL,3 LAl(SH) 2 6a [L = N(Ar)C(Me)CHC(Me)N(Ar), Ar = 2,6‐ i Pr 2 C 6 H 3 ); (RAlE) 2 (R = 2,4,6‐ t Bu 3 C 6 H 2 , E = S;5 R = N(SiMe 3 )C(Ph)C(SiMe 3 ) 2 ,6b 2,6‐(Et 2 NCH 2 ) 2 C 6 H 3 , 2‐Et 2 NCH 2 ‐6‐MeC 6 H 3 ;6c E = Se, Te], trans ‐[{Me 3 N(H)Al(μ‐E)} 2 ] (E = Se, Te),4b trans ‐[{Me 3 N(PhTe)Al(μ‐Se)} 2 ];4c [(η 1 ‐3,5‐ t Bu 2 pz(μ‐Al)H] 2 E (E = S, Se, Te);6d Me 3 NAl(ER) 3 (E = Se, R = Et, Ph, CH 2 Ph; E = Te, R = Ph)4a and Al 4 Se 5 (H) 2 (NMe 3 ) 4 4c} showed a rich chemistry. Although further reaction of the dimeric chalcogenidoalane, trans ‐[{Me 3 N(H)Al(μ‐E)} 2 ] (E = Se, Te) with chalcogen or organochalcogenides has been investigated,4b studies of the reaction of bulky, monomeric aluminum monohydrides with chalcogens, which might generate the corresponding monomeric Al‐EH moieties, have not been reported so far.…”
