An improved catalyst for the cyclization/hydrosilylation of functionalized 1,6-dienes employing dimethylphenylsilane
A 1:1 mixture of (Me 4 -phen)Pd(Me)Cl [Me 4 -phen=3,4,7,8-tetramethyl-1,10-phenanthroline] and NaBAr 4 [Ar=3,5-C 6 H 3 (CF 3 ) 2 ] catalyzed the cyclization/hydrosilylation of functionalized 1,6-dienes with dimethylphenylsilane within minutes at room temperature to form silylated cyclopentanes in good yield with high trans-selectivity.
