Reasoning 



R1C2 is the only square in row 1 that can be <7>

R7C5 is the only square in row 7 that can be <7>

R5C1 is the only square in column 1 that can be <7>

R8C1 is the only square in column 1 that can be <8>

R8C4 is the only square in column 4 that can be <3>

R8C5 is the only square in column 5 that can be <4>

Squares R2C6 and R8C6 in column 6 form a simple naked pair. These 2 squares both contain the 2 possibilities <56>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R4C6 - removing <56> from <5678> leaving <78>

R6C6 - removing <56> from <5678> leaving <78>

Squares R4C6 and R6C6 in block 5 form a simple naked pair. These 2 squares both contain the 2 possibilities <78>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R5C5 - removing <8> from <168> leaving <16>

Intersection of column 1 with block 1. The value <5> only appears in one or more of squares R1C1, R2C1 and R3C1 of column 1. These squares are the ones that intersect with block 1. Thus, the other (non-intersecting) squares of block 1 cannot contain this value.
