What reagents could be used to carry out the following syntheses?

Step-by-Step Solution

Solution 1

The alkyne undergoes different reactions with different reagents and produces various products. The reaction chart is drawn below.

(a) When an alkyne undergoes an addition reaction, it produces the bromo-substituted alkene.

(b) The reduction of the alkyne in the presence of a Lindlar catalyst produces alkene which undergoes an addition reaction and produces a halo alkene.

(c) The terminal alkyne undergoes the water addition in the presence of and yields an enol, which immediately converts into a ketone.

(d) The hydrogenation of alkyne in the presence of excess and metal catalyst such as produces an alkane.

(e) The alkyne can be converted into alkene in the presence of and Lindlar catalyst. So,

(f) When alkyne reacts with excess of, the added to the sp carbon having hydrogen atom of the alkyne and produces the dibromo compound.

The reaction diagram is drawn below and reagents are listed below of the diagram to synthesize the various products.
