In situ Grignard reactions of 1,8-(ClCH2)2C10H6 have yielded 2,3-dihydro-2,2-dimethyl-2-silaphenalene, which can be selectively monolithiated at the 1-position, and 1,8-(Me3SiCH2)2C10H6, a compound readily dilithiated and subsequently converted into the zirconium and hafnium metallacycles, meso-; the dilithium complex is converted into the complex containing a silicon heterocycle dicarbanion and characterized as the substituted silaphenalene, the same product as the ClSiMe3 adduct of mono-lithiated silaphenalene.

The complexes 2> (9) (tmen=NNN'N'-tetramethylethylenediamine) and (13) have been prepared via metallation of species formed by in situ Grignard trapping reactions of 1,8-(ClCH2)2C10H6 with SiMe3Cl and SiMe2Cl2 respectively; synthesis of the siline, meso- from (9) is also described.In hexane, (9) decomposes to (10) to yield the compound on the addition of aqueous HCl, the same product as that obtained from a reaction of (13) with SiMe3Cl.The nature of (10) has been established by X-ray structure determination of two polymorphs, α and β, which differ both in the mode of interaction of the Li(tmen)(+) moieties with the carbanion 6:η3 (α), cf. η4:η3 (β)> and the conformation of the heterocyclic ring.

Mild and efficient procedures have been developed for synthesis of 1,8-naphthalide and 1,8-naphthalenedimethanol. In an ice-water bath, 1,8-naphthalide was prepared from 1,8-naphthlic anhydride using LiAlH 4 as reducing agent. 1,8-Naphthalenedi
