Interpretation Introduction

Interpretation:

The effect of addition of Lewis acid BF3 before the reduction of S-ethyl thiobenzoate (A) is to be explained.

Concept introduction:

The lithium aluminum hydride reduces the thioacetate to thiol similar to ester reduction. If the reduction of thioacetate carried out by addition of Lewis acid BF3 it gives cyclohexyl ethyl sulfide due to formation of tetrahedral intermediate having oxygen-boron bond.

Triphenylmethanol is insoluble in water, but when it is treated with concentrated sulfuric acid, a bright yellow solution results. As this yellow solution is diluted with water, its color disappears and a precipitate of triphenylmethanol reappears. Suggest a structure for the bright yellow species, and explain this unusual behavior.
Compound A has the molecular formula C14H25Br and was obtained by reaction of sodium acetylide (HC≡CNa) )with 1,12-dibromododecane. On treatment of compound A with sodium amide, it was converted to compound B (C14H24). Ozonolysis of compound B gave the diacid HO2C(CH2)12CO2H. Catalytic hydrogenation of compound B over Lindlar palladium gave compound C (C14H26), while hydrogenation over platinum gave compound D (C14H28). Sodium-ammonia reduction of compound B gave compound E (C14H26). Both C and E yielded O═CH(CH2)12CH═O on ozonolysis. Assign structures to compound A through E so as to be consistent with the observed transformations.
