When treated with dialkyl ethers, [(BDI)Ca-μ-H-Zn(t-Bu)2(η6-C7H8)] (BDI = HC{C(Me)NDipp}2 initiates a sequence of twofold ether dealkylation and oxide sequestration as tert-butoxide in a process pred...

The β-diketiminato calcium hydride dimer, [(BDI)CaH]2 (BDI = HC{(Me)CNDipp}2; Dipp = 2,6-i-Pr2C6H3), reacts with [ZnTMP2] in the presence of terminal alkynes to provide a structurally diverse series of heterobimetallic calcium–zinc acetylide derivatives. Reactions employing two equivalents of alkyne yield the dialkynyl(hydrido)zincates, [(BDI)Ca(μ-C≡CR)(μ-TMP)Zn(μ-H)]2 (R = nBu, Ph), which undergo ligand redistribution to afford the corresponding β-diketiminato calcium acetylides. Conversely, use of four equivalents of alkyne results in further substitution at zinc to provide the tetrakis(alkynyl)zincates, [(BDI)Ca(μ-C≡CnBu)2Zn(μ-H)]2 and [(BDI)Ca(μ-C≡CPh)2Zn(μ-C≡CPh)2Ca(BDI)]. In contrast, an attempt to synthesize a similarly higher order calcium zincate but containing differentiated alkynyl substituents, by reaction of [(BDI)Ca(μ-C≡CnBu)(μ-TMP)Zn(μ-H)]2 and PhC≡CH, provided [(THF)2Ca(μ-C≡CPh)3Zn(CH2Ph)]2, resulting from toluene activation and after addition of THF as the only identifiable product.

[(BDI)Ca-μ-H]2 (BDI = HC{(Me)CNDipp}2, Dipp = 2,6-i-Pr2C6H3), has been employed to synthesize diorganophosphido- and bis(trimethylsilyl)phosphidocalcium derivatives. Reaction with two equivalents of P...

The C-tert-butyl substituted azacyclopropenylaluminate, [(SiNDipp)Al-η2-{NCt-Bu}K]∞ (SiNDipp = (CH2SiMe2NDipp)2) reacts with both aryl- and alkyl-substituted nitriles. In contrast to previously reported attempts to effect C–C bond formation between two dissimilar nitriles, these reactions enable the completely discriminating heterocoupling of t-BuCN to provide diazabutadienylaluminate dianions that bear two differentiated N═C substituents.
