Synthetic and reactivity studies of hetero-tri-anionic sodium zincates.
Francos J, Kennedy AR, O'Hara CT. Francos J, et al. Dalton Trans. 2016 Apr 14;45(14):6222-33. doi: 10.1039/c5dt04329h. Epub 2015 Dec 15. Dalton Trans. 2016. PMID: 26666657 Free article.
The synthesis and characterisation of several sodium zincate complexes are reported. The all-alkyl monomeric sodium zincate, (PMEDTA).Na(mu-CH2SiMe3)Zn(t)Bu22, is prepared by combining equimolar quantities of (t)Bu2Zn, (n)BuNa and PMDETA (N,N,N',N'',N' …

Neutral zinc, lower-order zincate and higher-order zincate derivatives of pyrrole: synthesis and structural characterisation of zinc complexes with one, two, three or four pyrrolyl ligands.
Garden JA, Kennedy AR, Mulvey RE, Robertson SD. Garden JA, et al. Dalton Trans. 2011 Nov 28;40(44):11945-54. doi: 10.1039/c1dt11430a. Epub 2011 Oct 6. Dalton Trans. 2011. PMID: 21976071
From their crystal structures, the 1 : 1, Na:Zn complex 3 can be classified as a lower-order zincate having three pyrrolyl ligands bound to zinc in a polymeric chain arrangement, while the 2 : 1, Na:Zn complexes 4 and 5 are molecular higher-order zincates having Zn …

Assessing the reactivity of sodium zincate [(TMEDA)Na(TMP)Zn(t)Bu2] towards benzoylferrocene: deprotonative metalation vs. alkylation reactions.
Hevia E, Kennedy AR, McCall MD. Hevia E, et al. Dalton Trans. 2012 Jan 7;41(1):98-103. doi: 10.1039/c1dt11465d. Epub 2011 Oct 24. Dalton Trans. 2012. PMID: 22024728
Exploring the reactivity of the mixed-metal reagent [(TMEDA)Na(TMP)Zn(t)Bu(2)] (1) towards substituted metallocene benzoylferrocene 2, this study has found that two competing reactivity pathways are available for the sodium TMP-zincate, namely (i) remote 1,6-nucleop …
