Synthesis and structure of unassociated mono-, di-, and trithiolate derivatives of aluminum and gallium: Investigation of Al-S and Ga-S π-bonding

The synthesis and characterization of several sterically crowded aluminum and gallium thiolates are described. The major reason for these studies was the investigation of the possible occurrence of .-bonding in Al-S and Ga-S bonds and the determination of the steric requirements for the isolation of monomeric heavier main group 3 thiolates in the solid state. The compounds examined were RA1(SMes*)2 (R = n-Bu, 1; t-Bu, 2), Mes*2GaSR (Mes* = 2,4,6-t-Bu3C6H2, R = Me, 3; Ph, 4), n-BuGa(SMes*)2, (5) (t-Bu2AlSTrip)2 (6) (Trip = 2,4,6-t-Pr3C6H2), (THF)Al(STrip)3 (7). They were characterized by X-ray crystallography (1-3, 5-7) and by NMR and IR spectroscopy. The data indicate that the M-S, p-p, π-bonding is weak and has an upper limit of 8-9 kcal mol-1. Restricted rotation around an M-S bond was detected only in the cases of Mes*2GaSMe (3) and Mes*2-GaSPh (4). Crystal data at 130 K with Mo Kα (λ = 0.710 69 A?) (2, 5-7) or Cu Kα (λ= 1.541 78 A?)
