Resumen

The reaction of tert‑butyldiallylphosphine with [Os₃(CO)₁₀(CH₃CN)₂] give the compounds [Os₃(CO)₁₁{κ(P)-^tBuP(CH₂CH[dbnd]CH₂)₂}] 1a, [Os₃(CO)₁₁{κ(P)-^tBuP(CH[dbnd]CHCH₃)₂}] 1b, [Os₃(CO)₁₀{κ(P)-^tBuP(CH₂CH[dbnd]CH₂)₂}₂] 2, diastereoisomers [Os₃(CO)₁₀{µ:η²-κ³(P,C²,C³)-^tBuP(CH₂CH[dbnd]CH₂)₂}] (3a Sp, 3b Rp) and [Os₃(CO)₉{µ:η²-κ³(P,C²,C³)-^tBuP(CH₂CH[dbnd]CH₂)₂)(κ(P)-^tBuP(CH₂CH[dbnd]CH₂)₂}] (4a Sp, 4b Rp). Thermolysis of 2 or 3 gave the complexes [Os₃(CO)₈(μ-H){μ₃:η¹:η²:η²-κ⁵(P,C²,C³,C⁵,C⁶)-P(CH₂CH[dbnd]CH₂)(CH₂C[dbnd]CH₂)}] 5 and diastereoisomers [Os₃(CO)₈(µ-H)₂{µ₃:η¹:η¹:η²-κ³(P,C²,C³)-^tBuP(CH₂CH[dbnd]CH₂)(C[dbnd]CHCH₂)}] (6a Sp, 6b Rp). 1a, 1b, 3a, 5 and 6a which were characterized by X-ray analysis. To the best of our knowledge, 1b is the first characterized structure involving isomerization of the double bond of the allylic substituent at room temperature in the case of metallic clusters. X-ray coordinates were used to study the possible reaction mechanisms through computational calculations at the MN15L/def2svp level of theory, obtaining good agreement between experimental and computational results.
