Efficient One-Pot Synthesis of Propargylstannanes from Propargylic Alcohol Derivatives via Allenyltitaniums.

-The reaction of propargylic carbonates (I) with a Ti(OiPr) 4 /iPr-MgCl reagent combination followed by treatment with Bu 3 SnCl affords mixtures of propargylstannanes (III) and allenylstannanes (IV). In most cases the former are by far dominant. -(AN,
