Thiolation of aldehydes and ketones general procedure

Sulfides can be prepared from alcohols. A convenient conversion under mild conditions and in high yields has been published [20]. The work-up is particularly simple. 

Efficient procedures for the direct preparation of allyl sulfides from allylic alcohols have also been reported [21]. 

The radical addition of thiols to alkenes, another general route to sulfides, was found [22] to be initiated by 9-BBN, leading to a remarkably efficient and simple method for the preparation of dialkyl sulfides.
