- Coordination Compounds of Organometallic Bases of Group(IV) Elements: Part XI-Reactions of N,N'-(Phenyl/o-chlorophenyl/p-methylphenyl/benzyl/diethyl)-1,1-di-n-propoxy/n-butoxy-silanediamines with Tin(IV) and Titanium(IV) Chlorides at -10 deg C

The title reactions in 1:1 molar ratio in petroleum ether (40-60 deg) afford adducts having rearranged bases with composition where R = C3H7 or n-C4H9; R' = C6H5CH2, o-ClC6H4 or p-CH3C6H4; n = 0 or 1; and x = 2 or 3 as evidenced by elemental analyses, IR and PMR spectral data as well as base exchange reactions.Filtrates of these reactions after keeping at room temperature for 48-72 hr, give solid complexes of the type in each case.The reaction with the tertiary amines such as N,N'-diethyl-1,1-di-n-propoxy/di-n-butoxysilanediamine form normal 1:1 adducts 2*MCl4> and no base rearrangement is observed.A tentative mechanism of the disproportionation reactions is proposed.
