A mixture of 8 mg (0.01 mmol) of PdCl2[(R)-BlNAP] and 1 g (4 mmol) of l,l-dichloro-1-phenyl-2,2,2-trimethyldisilane in 2mL of benzene is stirred for 15 min under nitrogen. To the resulting clear yellow solution is added 0.29 g (2 mmol) of ( )-l-phcnyl-2-butcnonc. The mixture is heated under reflux for 2 h the progress of the disilylation can be monitored by GLC. 2mL of diethyl ether is added, the mixture is cooled to —70 °C and 6.2 mL of a 1.9 M solution (12 mmol) of methyllithium in diethyl ether is added. The mixture is stirred at - 70 °C for 10 min then quenched with dilute hydrochloric acid. Extraction with diethyl ether followed by preparative TLC (silica gel, hexane/diethvl ether 5 1) gives the product yield 0.41 g (72%) [a]jy° 11.2 (c = 1.3. CHC1,).
