Source of material

The synthesis of [Cp*Al]4(Cp* = 1,2,3,4,5-pentamethylcyclopenta-2,4-dien-1-yl) was performed according to the previously reported procedure [5]. A mixture of [Cp*Al]4 and Bpin–CH=C=CH2 (Bpin = 4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl) in C6D6 in a dried J–Young Tube was heated at 80 °C under argon for 2 h. The compound was crystallized from a 1/10 mixture of hexane/C6D6 to afford colorless crystals.

Experimental details

A suitable crystal was selected and mounted on a Bruker APEX–II CCD diffractometer. The crystal was kept at 170.0 K during data collection. Using OLEX2, the structure was solved with the ShelXT structure solution program using Intrinsic Phasing and refined with the ShelXT refinement package using Least Squares minimisation.

Comment

Due to transition metal-like reactivities, the development of low-valent and low-coordinated Al(I) compounds with high reactivity has made remarkable progress in recent years. In 1991, Schnöckel et al. reported that the first monovalent aluminum compound [Cp*Al]4 has successfully been synthesized, which opened a new chapter of aluminum chemistry [6], [7], [8]. Subsequent studies revealed that [Cp*Al]4 not only performs as a neutral ligand to stabilize transition metals [9], [10], [11], [12], but also exhibits high reactivity to activate small molecules, such as O2, S8, Se, Te, N2O, P4, and CO2 [13], [14], [15], [16]. Since diene is isoelectronic with CO2, we demonstrated that the C=C bond activation of Bpin–CH=C=CH2 by [Cp*Al]4 can be achieved to obtain the title compound. The title compound is a product of the activation of a C=C double bond in BPin–CH=C=CH2 by [Cp*Al]4. The structure of the product contains an Al–C–C–Al–C–C six-membered ring, in which the C–C bond length is 1.4792(15) Å and the Al–C bond length is 2.0160(12) Å. The C–C bond outside the ring has a bond length of 1.3672(17) Å. These bond lengths are all within the expected range.
