In first reaction first step is metal insertion reaction and metal get inserted and there is formation of the carbanion takes place which attacks epoxide and then acidic treatment gives alcohol which on mild oxidation with PCC gives aldehdye.
In second reaction first step is reduction using metal of aldehyde to alcohol and the NaH so hydride attacks H of OH to form Na alkoxide and that react with benzyl chloride to form benzyl phenyl ether.
All the reactions are shown as below;
